Irwin IWAF243516 5/16 In Magnetic Nut Driver, 2-9/16 In.

The Irwin IWAF243516 5/16 In Magnetic Nut Driver is a 2-9/16 In. long nutsetter built with a 1/4-inch quick-change hex shank that fits into all types of impact drivers and rotary drivers. Its lobular tip design creates extra clearance around the corners of hexagonal fasteners, an area where paint build-up commonly interferes with a clean, tight fit, and the driver engages the flats of the fastener from the side rather than forcing the corners to turn, which helps maintain the true shape of the fastener over repeated use. Sized for 5/16 In. hexagonal head fasteners, this Irwin nut driver is intended for use with sheet metal screws and other hex-head hardware on professional job sites and DIY projects alike.

Key Features

  • Driver Size: 5/16 In. hex nutsetter with an overall length of 2-9/16 In. for reaching recessed and set-back fasteners.

  • Lobular Design: Provides more clearance on the corners of the fastener where paint build-up often occurs, helping keep a clean, secure fit.
  • Side-Driving Engagement: Drives fasteners from the side rather than forcing the corners to turn, which maintains the true shape of the fastener rather than rounding it out.
  • Magnetic Tip: Magnetic hex tip helps hold sheet metal screws and other hex fasteners in place during driving.
  • Fastener Compatibility: Designed for use with sheet metal screws and other hexagonal head fasteners.

Irwin IWAF243516 – Frequently Asked Questions

1) Will the Irwin IWAF243516 nutsetter fit my impact driver?
Yes. The IWAF243516 has a 1/4 inch hex quick-change shank, so it drops into any impact driver or rotary driver chuck or collet that takes standard 1/4 inch hex bits. No adapter needed.
2) Does this nutsetter hold the screw by itself so I can start it one-handed?
Yes, the hex socket has a magnetic tip that holds sheet metal screws and other hex fasteners in place while you start the drive. That matters on roof panel and ductwork runs where you are on a ladder with one hand on the tool.
3) Will a nutsetter round off painted hex screws when I back them out?
The lobular tip on this Irwin driver is built for exactly that problem. The lobes give extra clearance at the corners of the hex head where paint builds up, and the socket grips the flats from the side instead of loading the corners, so the fastener keeps its shape over repeated driving and removal. On painted panel screws that is the difference between reusing the fastener and drilling it out.
4) Should I use a magnetic nutsetter or a socket on an adapter for hex-head sheet metal screws?
For sheet metal screws, the nutsetter is the right call. A 1/4 inch hex shank nutsetter like the IWAF243516 goes straight into the driver with no socket adapter stack, so there is less runout and less chance of the bit walking off a thin panel, and the magnetic tip starts the screw for you. Sockets on a square-drive adapter make sense when you are torquing nuts and bolts, not driving self-tappers.
5) What is the exact part number to order the Irwin 5/16 magnetic nut driver?
Order Irwin manufacturer part number IWAF243516. That is the 5/16 inch magnetic nutsetter, 2-9/16 inches long, with the 1/4 inch hex quick-change shank.
