Wera 840/4 IMP DC Hex-Plus DIY Impaktor Bits 4 x 50 mm Pack of 5 | 05057644001
Wera 840/4 IMP DC Hex-Plus Impaktor bits (4.0mm x 50mm), pack of 5 – 05057644001
Wera 05057644001 is a set of 840/4 IMP DC Hex-Plus Impaktor bits designed for driving socket head screws with impact drivers, helping provide a longer service life under demanding use. The diamond-coated tip is designed to increase grip in the screw head to reduce cam-out when driving fasteners.
These 50mm screwdriver bits use Wera Hex-Plus geometry to increase the contact surface in the screw head, helping reduce the notching effect and minimise damage to the fastener. Ideal for trades and DIY users who want a reliable impact-ready bit for repeated fastening jobs.
Key Features
- Hex-Plus profile: Designed to increase contact surface in hex socket screws and reduce wear on the screw head.
- Impaktor technology: Built for above-average service life, including use in demanding impact applications.
- Diamond coating: Rough coating on the tip increases friction for a more secure fit and reduced cam-out.
- Impact-driver suitable: Particularly suitable for use with customary impact drivers.
- Take it easy tool finder: Colour coding by profile and size for faster selection in the tool bag.
- 1/4" hex drive: Standard hexagon drive for compatibility with common bit holders.
