Irwin IWAF34238 Magnetic Nutsetter 3/8 Inch Hex Bit

Product Description

The IRWIN IWAF34238 is a magnetic nutsetter bit designed for use with power screwdrivers, impact drivers, and drill/drivers. It features a 3/8 inch hex nut-driving end and a 1/4 inch hex shank for compatibility with standard quick-change bit holders. The overall length is 1-7/8 inches. The integrated magnet holds fasteners securely during driving, reducing drop and improving placement accuracy in tight or overhead work areas. This bit is suited for HVAC techs, electricians, plumbers, and other trade professionals who regularly drive hex-head sheet metal screws, machine screws, and similar fasteners during installation and service work.

This nutsetter is well suited for residential and light commercial applications where quick, consistent hex fastener driving is required. Common uses include securing electrical panels, ductwork flanges, junction box covers, pipe hangers, and equipment mounting hardware. The 1/4 inch hex shank fits standard power tool bit holders, making it a drop-in addition to any service kit. Its compact 1-7/8 inch overall length works in confined spaces where longer nutsetters would be restricted.

Key Features

• 3/8 inch hex drive for standard hex-head fasteners and sheet metal screws

Compatibility

Designed as an OEM-style replacement or supplemental bit for use with standard 1/4 inch hex quick-change bit holders found on power screwdrivers, drill/drivers, and impact drivers.

Installation Notes

Install this bit into a 1/4 inch hex quick-change chuck before applying power to the tool. Ensure the fastener is seated fully in the hex recess before driving to avoid cam-out or fastener damage. No special tools or trade licensing is required, but follow applicable electrical or mechanical codes when installing hardware in energized or pressurized systems. Always de-energize electrical panels and shut off mechanical systems before driving fasteners into or adjacent to live components.
