Irwin IR3547521C Magnetic Nut Setter 3/8 in Drive

Product Description

The IRWIN IR3547521C is a 3/8 inch magnetic nut setter designed for fast, secure fastener driving in trade and light industrial applications. The integrated magnet holds fasteners in place during placement, reducing dropped hardware and improving single-handed operation. At 1-7/8 inches overall length (OAL), this is a compact driver suited for use in standard drills and impact-rated hex chuck tools. Electricians, HVAC technicians, plumbers, and general contractors reach for magnetic nut setters when installing panel covers, equipment enclosures, and sheet metal assemblies. Sold individually as a single piece.

This nut setter fits standard 1/4 inch hex shank power tools, including cordless drills and drivers commonly used on residential and light commercial job sites. Its compact OAL makes it practical in tighter spaces where longer bits would be awkward. Typical applications include driving hex head sheet metal screws, machine screws, and hex bolts in HVAC ductwork, electrical enclosures, and plumbing access panels. The magnetic tip retains the fastener during positioning, speeding up repetitive fastening tasks.

Installation Notes

Magnetic nut setters are installed and used by electricians, HVAC technicians, and general tradespeople using cordless or corded power drivers.
