Wiha 79446 Hex Drive Bit Set 10 Piece

Product Description

The WIHA 79446 is a 10-piece hex drive bit set designed for fastening and driving applications across a wide range of trade and industrial work. Constructed from steel with a chrome finish, this set includes hex inch sizes covering 1/16, 5/64, 3/32, 7/64, 1/8, 9/64, 5/32, and 3/16 inches, as well as 1/4 and 7/32 inch bits. The hex point geometry provides positive engagement with fastener heads, reducing cam-out and wear during repeated use. Electricians, HVAC technicians, plumbers, and general tradespeople use this set for panel work, equipment assembly, and service calls where a variety of hex sizes are needed in one kit. The set weighs approximately 0.27 pounds.

This hex drive bit set suits residential and light commercial applications where hex-head fasteners are common. Typical use scenarios include equipment maintenance, control panel assembly, and mechanical fastening in HVAC, electrical, and plumbing service work. The range of included sizes — from 1/16 inch through 3/16 inch plus 7/32 and 1/4 inch — makes this set practical for technicians who encounter varied fastener sizes in the field without carrying individual bits.

Installation Notes

This bit set is intended for use with standard 1/4 inch hex shank drivers, impact drivers, or manual bit holders. Always confirm the bit size matches the fastener before applying torque to avoid fastener damage. De-energize or power down any equipment before accessing fasteners on electrical or mechanical components. Inspect bits for wear or deformation before use and replace any damaged bits to maintain proper fastener engagement.
