Wiha 75971 68 Piece Screwdriver Insert Bit Set

Product Description

The WIHA 75971 is a 68-piece micro bit set designed for precision fastening work across a wide range of drive types. The set covers Hex, Phillips, Slotted, Torx, Pentalobe, and Nut Driver profiles, making it a compact solution for service technicians who encounter varied fastener types on a single job. The kit includes a magnetic 1/4 inch to 4 mm adapter and a precision handle, so it is ready for use directly out of the case. Hex sizes run from 0.05 to 5/32 inch, Torx sizes cover T-1 through T-20, and Phillips sizes span 000 through 2. At 0.96 pounds, the set is portable enough to carry in a service bag or tool case.

This bit set is suited for electronics assembly, appliance service, HVAC controls, low-voltage wiring panel work, and any trade application requiring small-format fastener access. The micro-size range makes it particularly useful when working inside control boards, terminal enclosures, or equipment with proprietary fastener heads such as Pentalobe. Electricians, HVAC technicians, and appliance service pros will find the multi-tip coverage practical for reducing the number of individual bits carried on a service call.

Installation Notes

Always power down or de-energize equipment before working on fasteners inside electrical panels, control boards, or HVAC components. Use the precision handle for low-torque, controlled driving to avoid stripping small fasteners. Insert bits should be seated fully and confirmed secure in the bit holder before applying torque. Handle and store bits in the provided case to protect tips from damage.
