Wera 05057631001 Square Recess Power Screwdriver Bit

Product Description

The WERA 05057631001 is a square recess power screwdriver bit designed for use with power tools and impact drivers in professional trade applications. With a 0.25 inch drive size and a 1 inch overall length, this bit is suited for high-torque fastening tasks where precision fit and bit retention matter. The square recess profile provides positive engagement with square-drive fasteners, reducing cam-out during power driving.

This bit is appropriate for residential and light commercial applications where square-drive fasteners are standard. Its compact 1 inch overall length makes it compatible with most bit holders, quick-change chucks, and power screwdriver attachments used in the field. It is well suited for production fastening, service work, and repetitive assembly tasks.

Installation Notes

This bit is installed by trade professionals using power screwdrivers, drills, or impact drivers equipped with a compatible 0.25 inch hex bit holder. Ensure the bit is fully seated in the chuck or holder before driving to prevent slipping or fastener damage. Inspect the bit tip for wear before use, as a worn square recess profile will increase cam-out and damage fastener heads. Follow applicable tool safety guidelines and manufacturer torque recommendations for the fasteners being driven.
