Irwin IR3547321C Magnetic Nutsetter 5/16 in 1-7/8 in Oal

Product Description

The IRWIN IR3547321C is a 5/16-inch magnetic nutsetter designed for fast, secure fastening in trade and construction applications. The integrated magnet holds nuts firmly on the driver tip, reducing dropped hardware and improving one-handed operation in tight spaces. At 1-7/8 inches overall length, this compact nutsetter fits standard hex-shank power drivers and impact-rated bit holders. Electricians, HVAC technicians, and general contractors reach for magnetic nutsetters when installing equipment panels, electrical boxes, duct flanges, and structural fasteners where nut retention and speed matter.

This nutsetter suits residential and light commercial jobsite use wherever 5/16-inch hex fasteners are common. Typical applications include equipment mounting, electrical enclosure assembly, duct system installation, and panel work. The short overall length of 1-7/8 inches makes it practical in confined areas where a longer driver would be obstructed. It is sold individually and is compatible with standard 1/4-inch hex quick-change driver systems found on most cordless drills and impact drivers.

Key Features

• 5/16-inch drive size fits standard hex nuts and sheet metal screws with matching head size
• Magnetic tip retains fasteners for single-handed placement and reduced drop risk
• 1-7/8-inch overall length suits confined installation spaces
• Compatible with 1/4-inch hex quick-change bit holders and standard drill chucks
• Sold as a single unit for targeted replacement or kit supplementation

Compatibility

Designed for use with standard 1/4-inch hex-shank quick-change driver systems on cordless drills and impact drivers commonly used in HVAC, electrical, and plumbing trade work.

Installation Notes

Insert the nutsetter into a 1/4-inch hex quick-change chuck or standard drill chuck before use. Verify the fastener is fully seated on the magnetic tip before driving to avoid cam-out or cross-threading. When using with an impact driver, confirm the nutsetter is rated for impact use before applying high-torque settings. Replace the nutsetter if the magnetic tip loses retention strength or if the hex drive shows visible wear.
