Wera 05057603001 840/1 IMP DC Hex-Plus Impaktor bits, 3mm x 25mm (10 pack)

Wera 05057603001 Impaktor insert bits are 1/4" hex driver bits designed for hexagon socket screws, helping tradespeople achieve a secure, controlled drive when using impact drivers and bit holders.

This 840/1 IMP DC set combines Hex-Plus geometry with a diamond-coated tip to improve grip in the screw head and reduce the chance of cam-out, making it a strong choice for repetitive fastening tasks in workshop and site use.

Key Features

• Hex-Plus profile: Designed to increase contact area in the screw head to help reduce wear and minimise damage during tightening and loosening.
• Impaktor technology: Built for above-average service life, even in demanding fastening applications.
• Diamond-coated tip: Enhanced friction helps the bit “bite” into the screw head for a more secure fit and reduced cam-out.
• Impact-driver suitable: Particularly suitable for use with customary impact drivers.
• 1/4" hex shank: Suitable for holders as per DIN ISO 1173-D 6.3.
• Take it easy tool finder: Colour coding helps you identify profile and size quickly in the toolbag or on the bench.
