Irwin IWAF34438 Magnetic Nutsetter Bit 3/8 in Hex

Product Description

The IRWIN IWAF34438 is a magnetic nutsetter bit designed for use with power screwdrivers and impact-ready drivers in trade and production work. The 3/8 inch hex drive size seats hex-head fasteners securely, while the built-in magnetic retention holds the nut in place during placement and driving. The bit measures 4 inches in overall length, providing enough reach for recessed fastener locations. With a 1/4 inch hex shank, it fits standard quick-change bit holders and most cordless drills, impact drivers, and screw guns. Electricians, HVAC technicians, plumbers, and general contractors use this type of nutsetter for panel fasteners, equipment mounting hardware, and sheet metal applications.

This nutsetter bit is suited for light commercial and residential installations where hex-head sheet metal screws, machine bolts, or equipment fasteners are driven repeatedly. The 4 inch length gives clearance in tight cabinet or panel spaces where a shorter bit would not seat properly. Sold as a single bit, it is a direct replacement or supplemental addition to a power driver bit set.

Installation Notes

Install and remove nutsetter bits only when the driver tool is powered off or the battery is removed. Seat the 1/4 inch hex shank fully into the bit holder before operation to prevent slippage. Do not use nutsetter bits to exceed the torque rating of the driver tool or the fastener specification. Inspect the magnetic tip periodically for wear or debris that could affect fastener retention.
