Wiha 70442 Magnetic Nutsetter 7mm Hex 2.125 in Steel

Product Description

The WIHA 70442 is a magnetic nutsetter power screwdriver bit designed for use with electric and pneumatic power drivers in mechanical, electrical, and HVAC installation work. Built from steel, this bit measures 2.125 inches in overall length and accepts a 0.25-inch drive. The integrated magnetic tip holds fasteners securely during placement, reducing dropped hardware in confined spaces or elevated work. It is used by electricians, HVAC technicians, plumbers, and general trade contractors who rely on power drivers for repetitive fastening tasks.

This nutsetter is suited for light-duty to medium-duty power driving applications where a 7mm hex fastener is required. Common installation scenarios include panel assembly, equipment mounting, ductwork fastening, and electrical enclosure work. The single-piece format makes it a practical addition to a driver bit kit or job-site pouch. It is compatible with standard 0.25-inch hex quick-change bit holders used on most cordless and corded power screwdrivers.
