Wiha 70438 Magnetic Nutsetter Bit 5.50mm Hex Power Drive

Product Description

The WIHA 70438 is a magnetic nutsetter power screwdriver bit designed for use with power drivers and impact-ready hex chucks. It accepts a 0.25 inch (1/4 inch) hex drive and seats fasteners magnetically, keeping nuts and screws on the tip during placement. The 5.50mm hex size and 2.125 inch overall length make it a standard workhorse bit for production, mechanical, and electrical work. The magnetic retention reduces dropped fasteners in tight panel and conduit work, where one-handed fastening is often required.

This bit suits electricians, HVAC technicians, and general tradespeople who drive hex-head fasteners repeatedly with a power tool. It is well suited to sheet metal screws, equipment panel fasteners, and HVAC cabinet assembly. The 1/4 inch hex shank is compatible with standard quick-change chucks found on cordless drills, impact drivers, and dedicated power screwdrivers. It is packaged as a single bit and is available for order in single-unit quantities.
