Wiha 72538 Square Drive Insert Bit 2 Point 25 Mm 30 Pack

Product Description

The WIHA 72538 is a No. 2 square-drive screwdriver insert bit designed for use in power tools, impact drivers, and bit holders that accept a standard hex shank. Built from steel, each bit measures 25 mm in overall length, fitting the most common 1-inch insert bit format used in production and service work. This listing includes a pack of 30 bits, making it a practical stock item for shops, service vans, and job sites where high-volume fastening is routine. The hex drive interface ensures a secure seat in any compatible quick-change chuck, reducing slippage during high-torque applications.

The WIHA 72538 is suited for residential and commercial work where No. 2 square-drive fasteners are standard. Electricians, HVAC technicians, and general contractors frequently encounter square-drive screws in panel work, equipment mounting, and millwork. The 30-piece pack supports crew-level consumption without repeated individual reorders, and the 25 mm length fits most inline and right-angle bit holders without modification.

Installation Notes

Insert bits should be seated fully into the bit holder or quick-change chuck before use. Inspect each bit for wear or deformation before inserting into a powered tool. Use appropriate eye protection when operating power tools at high RPM. Worn or damaged bits should be replaced immediately to prevent fastener head damage or bit ejection.
