Screwdriver Bits
Impact driver bits are built to handle the brutal torque of power tools. Made from hardened steel with torsion zones and shock resistance, these bits power through tough fixings without snapping or stripping. Choose the right bit and get it done fast.
What Are These Bits Used For?
Designed for fast, accurate and repeatable screwdriving across the site:
- Timber Framing – Drive long screws and fixings into studwork, joists and rafters
- Plasterboard & OSB Fixing – Secure board to timber or metal track
- Furniture & Assembly – Fit hinges, brackets, legs and wall mounts
- Electrical & HVAC – Use magnetic or stubby bits in tight installs
Used By:
- Joiners, builders and drywall fixers
- Kitchen fitters and electricians
- Workshop techs and cabinetmakers
Choosing the Right Driver Bit
Match your bit to the tool, material and fixing type:
1. Torsion or Standard
Torsion bits flex under load to prevent snapping — ideal for impact drivers. Standard bits suit low-torque drills.
2. Head Type
PH2 is most common, but we stock PZ2, Torx, Hex, Slotted and more. Always match to screw for grip.
3. Length & Magnetic Grip
Choose stubby for access, long for reach, and magnetic if you’re fixing overhead or at awkward angles.

Screwdriver & Impact Bit FAQs
Do I need torsion bits for an impact driver?
Yes — torsion bits are specifically designed to absorb the twisting force. Standard bits can snap or strip under high torque.
What’s the most common bit size?
PH2 and PZ2 are the most used for wood screws and fixings. Most sets include multiple versions for quick swaps.
Are magnetic bits better?
They help a lot when working overhead or one-handed. But grip strength still depends on quality and screw head condition.
Can I use these in a combi drill?
Yes — impact bits can be used in any standard 1/4" hex chuck. They just last longer under pressure from impact drivers.
