Wiha 70437 Magnetic Nutsetter Bit 5mm Hex Steel

Product Description

The WIHA 70437 is a magnetic nutsetter power screwdriver bit designed for use with power drills and impact-ready screwdrivers in professional trade applications. Built from steel with a 0.25 inch (1/4 inch) drive size, this bit offers reliable torque transfer for driving hex fasteners. The 5mm hex size and 2.125 inch overall length make it a compact, versatile choice for electricians, HVAC technicians, plumbers, and general contractors who need consistent fastener control in tight spaces or repetitive production work. The integrated magnetic tip holds fasteners securely during placement.

This nutsetter bit is suited for residential and light commercial installation work where 5mm hex fasteners are common. Typical applications include panel and bracket assembly, equipment mounting, conduit fitting installation, and other mechanical fastening tasks encountered in HVAC, electrical, and plumbing service. The single-piece format makes it a straightforward replacement or addition to a bit set.

Installation Notes
