Irwin IR3547121C Magnetic Nut Setter 1/4 Inch Drive

Product Description

The IRWIN IR3547121C is a 1/4 inch magnetic nut setter designed for fast, secure fastener driving in electrical, HVAC, and mechanical trade work. The built-in magnet holds hex-head screws and nuts firmly on the bit tip, reducing dropped fasteners during overhead or tight-clearance installations. At 1-7/8 inches overall length, this is a compact driver suited for standard power screwdrivers, impact drivers, and drill/driver combos with a 1/4 inch hex shank. It is sold individually as a single piece.

This nut setter fits common trade applications where 1/4 inch hex-drive fasteners are standard — including electrical panel work, ductwork assembly, equipment mounting, and light structural fastening. The compact 1-7/8 inch overall length makes it practical in confined spaces such as junction boxes, control panels, and equipment access areas. Electricians, HVAC technicians, and general mechanical contractors regularly use magnetic nut setters of this type as part of a standard bit kit.

Key Features

• 1/4 inch hex drive fits standard power drills, screwdrivers, and impact drivers
• Magnetic tip retains hex-head fasteners during placement
• 1-7/8 inch overall length suits confined-space installations
• Single-piece packaging — no bulk quantity required

Compatibility

Designed as a standard 1/4 inch hex shank nut setter compatible with any power drill, screwdriver, or impact driver accepting 1/4 inch hex quick-change bits.

Installation Notes

No electrical or mechanical system shutdown is required for the tool itself, but always de-energize any panel or equipment before working in live electrical enclosures per NEC requirements. Confirm the bit shank seats fully in the tool chuck before applying torque. Inspect the magnetic tip periodically — accumulated metal debris can reduce holding strength and should be wiped clean before use.
