Wiha 75958 Precision Screwdriver Bit Set 36 Piece

Product Description

The WIHA 75958 is a 36-piece precision screwdriver bit set designed for technicians who need a broad range of drive types in a single kit. The set covers Phillips, slotted, square, and Torx drive formats, making it well-suited for equipment service, panel work, and component-level repair across HVAC, electrical, and general trade applications. Each bit is machined from steel with an oxide finish and features a magnetic tip for single-hand fastener placement. The 4.00 mm drive size and 4.25-inch overall length position these bits for precision work rather than high-torque driving.

This bit set is intended for trade professionals who regularly service equipment requiring small-format fasteners, including control boards, terminal enclosures, access panels, and electronic assemblies. The combination of Torx sizes T2, T3, T4, T6, and T8 alongside slotted, Phillips, and hex drive types covers the fastener mix commonly encountered in light commercial and residential equipment service. The precision style designation indicates these bits are optimized for low-torque, high-accuracy applications rather than impact or production driving.

Key Features

Compatibility

Designed for use in standard 4.00 mm precision bit holders and compatible handles accepting that drive size. Suitable for service of residential and light commercial equipment with small-format Phillips, slotted, square, and Torx fasteners.

Installation Notes

These bits are non-insulated and must not be used on or near energized conductors or live electrical components. De-energize and lock out equipment before accessing internal fasteners on any HVAC, electrical, or mechanical assembly. Use in a matching 4.00 mm precision bit driver or handle rated for the application. Bits are intended for hand-drive precision work and are not suitable for impact drivers.
