Wera 897/4 Impaktor Heavy Duty Tri Torsion Bit Holder

The Wera 897/4 Impaktor Heavy Duty Tri Torsion Bit Holder is a specialist 1/4" hex bit holder engineered to absorb the extreme impulse peaks generated by impact drivers and screwdriving robots.

At the core of this holder is a double-torsion spring mechanism that delivers a particularly effective torsion effect, protecting both the bit and the tool from the damaging stress of high-cycle dynamic applications. The stainless construction deliberately avoids small mechanical parts that are prone to failure under demanding conditions, making it a reliable choice for industrial assembly environments.

A retaining ring ensures a secure, consistent fit of the bit within the holder, while an integrated magnet provides additional fixing of both the bit and the screw during use. This combination of retention features makes it well suited to screwdriving robots and automated assembly lines where precision and repeatability are essential.

The holder accepts standard 1/4" hexagon head bits to DIN ISO 1173-C 6.3 and connects to power screwdrivers via a 1/4" hexagon drive compliant with DIN ISO 1173-F 6.3.

Features and Benefits:
• Double-torsion spring absorbs extreme impulse peaks for impact driver use
• Stainless construction with no small mechanical parts for maximum durability
• Retaining ring ensures consistent, secure bit fit in the holder
• Integrated magnet provides additional fixing of bit and screw
• Compatible with standard 1/4" hex bits (DIN ISO 1173-C 6.3)
• 1/4" hexagon drive suits power screwdrivers to DIN ISO 1173-F 6.3
