Irwin IWAF34638 Magnetic Nutsetter 3/8 Hex 6 in

Product Description

The IRWIN IWAF34638 is a magnetic nutsetter bit designed for use with power screwdrivers and impact-ready hex-shank drivers. It features a 3/8 inch hex drive interface, a 1/4 inch drive shank, and an overall length of 6 inches. The magnetic tip holds fasteners in place during driving, reducing dropped hardware in tight workspaces. This bit is used by electricians, HVAC technicians, plumbers, and general contractors who need reliable nut-driving performance with a power tool. The 6 inch length provides extended reach in confined installations where a shorter bit would not clear surrounding structure.

This nutsetter is suited for residential and light commercial applications where 3/8 inch hex fasteners are common. Typical uses include driving sheet metal screws in duct work, securing electrical enclosure hardware, attaching equipment mounting brackets, and similar repetitive fastening tasks. The 1/4 inch hex shank is compatible with standard quick-change bit holders and most cordless drill and driver chucks used in the trades.

Installation Notes

This bit is installed and removed by hand in any quick-change or standard 1/4 inch hex chuck. Ensure the driver is powered off and the trigger is locked before changing bits. Inspect the magnetic tip and bit socket for wear before use, as a damaged tip can strip fastener heads or cause the fastener to disengage mid-drive. Follow applicable codes such as the NEC or IFGC when driving fasteners in electrical or gas system assemblies.
