Nut Driver Bits Price Comparison 2026
Compare 182 nut driver bits from HAZET, Wera and Makita. Find the best price across top UK retailers and pick the right size for your job.
Nut driver bits occupy a surprisingly specific niche in any toolkit — they look like ordinary screwdriver bits but do the job of a socket wrench, gripping hex nuts and bolts directly from a drill or manual driver. The market here is dominated by two names: HAZET, which accounts for the lion's share of the catalogue with over 120 references, and Wera, whose smaller but premium range sits at a noticeably higher average price. If you're browsing this category for the first time, that split tells you something useful: HAZET offers breadth and solid German engineering at accessible prices, whilst Wera targets professionals who want tighter tolerances and longer service life.
Prices span a wide range — from 2 £ for a basic single bit up to 65 £ for a professional-grade set — but the vast majority of individual bits land between 8 £ and 11 £. That's the sweet spot where chrome-vanadium steel construction, decent hardness ratings and reliable hex drive shanks are all standard. Budget options from Yato sit well below 8 £ and are fine for occasional DIY use, but we'd steer anyone doing regular mechanical work away from them. The steel quality simply doesn't hold up under repeated torque cycles.
One thing worth flagging: shank compatibility is the most common source of frustration in this category. A 1/4" hex drive bit won't seat properly in a 3/8" chuck without an adapter, and using the wrong shank under load risks both the bit and the fastener. Before comparing prices, confirm what drive size your drill, impact driver or manual driver accepts. If you're also shopping for screwdriver bits or nut drivers, it's worth standardising your shank system across the board — it saves money and avoids adapter clutter.
For tradespeople and workshop regulars, multi-piece sets offer far better value than buying individual bits. The Wera KK 100 52-piece set is the standout example here — expensive upfront, but the cost per bit is competitive and the storage solution alone justifies the premium. Single bits make sense for replacements or when you need a specific socket size that's missing from an existing set. Check whether the bit is impact-rated if you're pairing it with a cordless impact driver — standard bits can shatter under shock loads, which is both dangerous and costly. Browse the full selection and compare live prices across UK retailers to find the right bit at the right price.
How to Choose the Right Nut Driver Bit
With 182 products listed and prices ranging from 2 £ to 65 £, picking the right nut driver bit is less about brand loyalty and more about matching the bit to your specific fastener, tool and working environment. Get the socket size or shank type wrong and you'll strip a nut before you've even started. Here's what actually matters.
Socket size — get this right first
This is the non-negotiable starting point. Nut driver bits are sized by the internal diameter of their working end — typically anywhere from 3mm up to 32mm for metric fasteners. Using a bit that's even 0.5mm too large will round off nut corners within a few turns. Check the fastener size before anything else. For automotive and general mechanical work, 8mm, 10mm, 12mm and 13mm are the most frequently needed sizes. If you're unsure, a multi-piece set covering the common range is a safer investment than guessing on a single bit.
Shank type and power tool compatibility
The shank is how the bit connects to your tool, and mismatches are the single most common buying mistake in this category. The 1/4" hex drive is the standard for most cordless drills and electric screwdrivers. The 3/8" and 1/2" hex drives are used with larger ratchets and impact wrenches. If you're using an impact driver specifically, check that the bit is explicitly impact-rated — standard bits are not designed for the shock loads these tools generate and can fracture without warning. Adapters exist but add play to the connection, which reduces torque accuracy.
Material and hardness (HRC rating)
Chrome-vanadium steel is the baseline you should expect from any bit priced above 8 £. It offers a good balance of hardness (typically 55–60 HRC), toughness and corrosion resistance. Below that price point, you're often looking at standard hardened steel, which wears faster and is more prone to deformation under sustained torque. For professional or high-frequency use, chrome-molybdenum steel (as used in some HAZET and Wera professional lines) provides even greater impact resistance. Avoid anything that doesn't specify its steel grade — it's usually a sign the manufacturer would rather you didn't know.
Bit length and access requirements
Standard bits (40–50mm) cover most general applications. But if you're working in engine bays, behind panels or in any confined space, a long (60–80mm) or extra-long (90–120mm) bit can make the difference between a five-minute job and a frustrating hour. Conversely, longer bits reduce torque control and can flex under load — don't default to the longest option available. Short bits (25–35mm) are worth having for surface-level fastening where rigidity matters more than reach.
Single bit vs. multi-piece set — the value calculation
Individual bits make sense for two scenarios: replacing a worn-out specific size, or filling a gap in an existing set. For everything else, a multi-piece set almost always wins on cost per bit. The Wera KK 100 at 52 pieces is the premium benchmark in this catalogue. Sets from HAZET in the 11 £ to 16 £ range offer solid coverage without the premium. One practical tip: check whether the set includes a storage rail or case — loose bits in a drawer are a fast route to losing the one size you need most.
- Budget picks (From 2 £ to 8 £) : Yato and Facom single bits sit here. Adequate for occasional DIY use — fitting flat-pack furniture, basic home repairs — but the steel quality and tolerances won't satisfy anyone doing regular mechanical work. Fine as a stopgap, not as a long-term investment.
- The sweet spot (From 8 £ to 11 £) : This is where most of the HAZET single-bit range lives, and it's genuinely good value. Chrome-vanadium steel construction, reliable hex drive shanks and multiple socket sizes available. The HAZET 880 and 850 series are typical examples — well-made, widely stocked by UK tool retailers, and competitively priced.
- Mid-range and specialist bits (From 11 £ to 16 £) : Longer HAZET bits, Wera individual pieces and Makita's 3-piece sets occupy this band. You're paying for tighter tolerances, better surface finishes and in some cases impact-rated construction. Worth the step up if you're using these bits regularly or with power tools.
- Professional sets and premium single bits (Over 16 £) : The Wera KK 100 52-piece set and HAZET's professional-grade bits with integrated sockets live here. Expensive upfront, but the cost per bit is competitive and build quality is noticeably superior. Aimed at tradespeople and workshop professionals who need reliability under sustained use. The Bosch accessories in this range are the outliers — premium pricing for a brand better known for its power tools than its bits.
Top products
- HAZET 8501-6 nut driver bit 1 pc(s) (HAZET) : The most widely stocked single bit in the catalogue and a reliable workhorse — solid chrome-vanadium construction at a fair price. Not the most exciting option, but it's the one most professionals reach for first.
- Wera KK 100 nut driver bit 52 pc(s) (Wera) : The premium set in this catalogue and genuinely worth the outlay for workshop professionals. Fifty-two pieces with Wera's characteristically tight tolerances and a proper storage solution. Overkill for occasional DIY, but excellent value per bit for daily use.
- Makita E-12354 nut driver bit 3 pc(s) (Makita) : A sensible three-piece set from a brand whose bits are optimised for its own cordless tools. Good choice if you're already in the Makita ecosystem, but not the obvious pick if your drill is a different brand — the value proposition weakens outside that context.
- HAZET 880-13 nut driver bit 1 pc(s) (HAZET) : One of the most useful individual sizes to own — 13mm covers standard M8 fasteners, making this a go-to replacement bit for automotive and general mechanical work. Priced well below the median, which makes it an easy recommendation.
- HAZET 1007S-1 nut driver bit 1 pc(s) (HAZET) : HAZET's professional-grade single bit at a noticeably higher price point — the step up in build quality and tolerance is real, but you'll only appreciate it under sustained professional use. Don't pay the premium for occasional jobs; do pay it if you're using it daily.

Frequently Asked Questions
What socket size nut driver bit do I need for standard M8 bolts?
For M8 bolts, you need a 13mm nut driver bit — that's the across-flats measurement of a standard M8 hex nut. It's one of the most commonly needed sizes in automotive and general mechanical work, and most HAZET and Wera sets include it as standard. If you're buying a single replacement bit, double-check the nut with a calliper first, as some M8 fasteners use 12mm heads depending on the standard they were manufactured to.
Can I use a standard nut driver bit with an impact driver?
No — using a standard nut driver bit with an impact driver is a genuine safety risk. Standard bits are not designed to absorb the sudden shock loads that impact drivers generate, and they can fracture under load, potentially sending fragments at high speed. Always look for bits explicitly labelled as impact-rated if you're using them with an impact driver or pneumatic tool. HAZET and Wera both produce impact-rated variants; they're identifiable by their torsion zone design and typically darker finish.
What's the difference between a nut driver bit and a regular screwdriver bit?
A nut driver bit has a socket-shaped working end designed to grip the outside of a hex nut or bolt head, whereas a screwdriver bit engages with a recess in the fastener head (Phillips, Torx, slotted, etc.). They use the same shank system and fit the same drivers, but they serve entirely different fastening tasks. If you need both, check out the screwdriver bits category alongside this one — many professional sets combine both types.
Is HAZET worth the price over cheaper alternatives like Yato?
For regular use, yes — HAZET is worth it. The price gap between HAZET and Yato is relatively modest in absolute terms (often just a few pounds per bit), but the difference in steel quality, tolerance and longevity is significant. Yato bits are manufactured to a lower hardness rating and tend to wear or deform faster under sustained torque. If you're using nut driver bits daily or with power tools, the HAZET range in the 8 £ to 11 £ band is the sensible choice. Yato is fine for the occasional job where precision and durability aren't critical.
What does '1/4" hex drive' mean and does it matter?
The 1/4" hex drive refers to the six-sided shank size on the bit — it's the part that slots into your drill, screwdriver or ratchet. It's the most common standard for cordless drills and electric screwdrivers in the UK, so most bits in this catalogue will fit your existing tools without an adapter. The 3/8" and 1/2" hex drives are used with larger ratchet handles and impact wrenches. Always check your tool's chuck size before buying — it's printed on the tool body or listed in the manual.
Are multi-piece nut driver bit sets actually better value than buying individual bits?
In most cases, yes — a multi-piece set works out cheaper per bit and gives you the sizes you didn't know you'd need. The Wera KK 100 52-piece set is the clearest example in this catalogue: the per-bit cost is competitive, and the integrated storage means you're not hunting through a drawer for the right size. That said, if you only ever use one or two specific sizes, buying individual HAZET bits in the 8 £ to 11 £ range is perfectly sensible and avoids paying for sizes that'll sit unused.
What pitfalls should I avoid when buying nut driver bits online?
The biggest trap is buying on price alone without checking socket size and shank compatibility — a bit that doesn't fit your fastener or your tool is worthless regardless of cost. Also watch out for listings that don't specify the steel grade: if the product description doesn't mention chrome-vanadium or chrome-molybdenum steel, assume it's basic hardened steel and price your expectations accordingly. Finally, don't use non-impact-rated bits with impact drivers — it's a false economy that ends with a broken bit and potentially a damaged fastener.
