Wera 05071103001 Hex Screwdriver Insert Bit

Product Description

The WERA 05071103001 is a metric hex screwdriver insert bit designed for use with 1/4 inch drive tools. Built from stainless steel, this bit delivers corrosion resistance and durability in demanding service environments. The Hex-Plus fastener interface is engineered to reduce contact stress on fastener flanks, which helps prevent rounding and extends the life of both the bit and the fastener. At 89 millimeters in blade length, it provides added reach in tight or deep access applications. Licensed tradespeople and field technicians working in HVAC, plumbing, electrical, and mechanical trades will find this bit a reliable addition to a professional bit set.

This insert bit is suited for metric hex fastener applications across residential and commercial service work. The 1/4 inch drive sizing makes it compatible with standard bit holders, extension bars, and power tool adapters commonly found on the job site. The stainless steel construction makes it appropriate for environments where moisture or chemical exposure is a concern, such as mechanical rooms, outdoor equipment panels, and pool equipment enclosures.

Installation Notes

Insert bits should be seated fully into the bit holder before applying torque to avoid cam-out or bit ejection. Inspect the bit tip for wear before use, as a worn Hex-Plus profile will not seat correctly in the fastener. This bit is intended for use by qualified tradespeople following applicable industry safety practices for hand and power tool operation.
