Irwin® Nutsetters stand apart from the competition by combining unsurpassed magnetic power and high-performance materials to give you total control of the fastener.

• Lobular design reduces stripping damage by driving the fastener on the sides instead of forcing the corners to turn
• Maintains the true shape of the fastener, dramatically reducing breakage and stripping damage
• Provides more clearance on the corners of the fastener where paint build-up can occur
• Magnetic nutsetters use magnets that are 4X more powerful than common magnets
• Positive retention of the screw improves installation rate
• Universal 1/4 in hex shank fits most power tools and quick-change chuck Adapters
• For sheet metal screws and other hexagonal head fasteners
