Irwin 3547 Magnetic Hex Nutsetter with Lobular Drive Design

Irwin 3547 Magnetic Hex Nutsetter with Lobular Drive Design

The Irwin 3547 Magnetic Hex Nutsetter is a precision-engineered driving tool built for use with sheet metal screws and other hexagonal head fasteners. Its distinctive lobular design drives the fastener along its sides rather than forcing the corners to rotate, which significantly reduces stripping damage compared to a standard hex socket. This nutsetter is available in 5/16 inch and 3/8 inch sizes, giving installers the flexibility to match the tool to the fastener size at hand, and each unit is packaged one per pack (Pack Qty: 1) for straightforward inventory management and replacement. The magnetic tip holds fasteners firmly in place for fast, accurate, one-handed driving, whether tackling sheet metal screw installation, general fabrication, or assembly work.

Key Features

• Lobular Drive Design: Engages the sides of the fastener instead of forcing the corners to turn, reducing stripping damage and extending fastener life.
• Improved Corner Clearance: Provides more clearance on the corners of the fastener where paint build-up can occur, helping maintain a secure, consistent drive.
• Broad Fastener Compatibility: Designed for use with sheet metal screws and other hexagonal head fasteners across a range of fastening tasks.
• Magnetic Tip Retention: Helps hold the fastener securely in place during driving, supporting faster, more efficient, one-handed operation.
• Available Sizes: Offered in 5/16 inch and 3/8 inch sizes to match a variety of hexagonal head fastener dimensions.
• Single-Unit Packaging: Packaged one per unit (Pack Qty: 1), making it easy to stock, restock, and replace as needed.
