Apex MDB-12 Magnetic Nutsetter 3/8 Inch Hex

Product Description

The APEX MDB-12 is a magnetic nutsetter bit designed for use with power screwdrivers and impact drivers in professional trade applications. The magnetic tip retains hex fasteners securely during driving, reducing dropped hardware in tight or overhead work. It features a 3/8 inch hex drive socket with a 1/4 inch hex shank and an overall length of 2-9/16 inches. This bit is suited for electricians, HVAC technicians, plumbers, and other trade professionals who routinely drive hex-head fasteners with power tools.

This nutsetter fits standard applications where 3/8 inch hex fasteners are common, including equipment panels, junction boxes, ductwork hardware, and mechanical connections. The 2-9/16 inch overall length provides enough reach for most standard fastening tasks without adding unnecessary extension. It is sold individually and is appropriate for both shop and field use.

Key Features

• Magnetic tip retains 3/8 inch hex fasteners during driving
• 1/4 inch hex shank for compatibility with standard power driver chucks
• 2-9/16 inch overall length suits general-purpose fastening depth

Compatibility

Designed as a standard magnetic nutsetter for use with 1/4 inch hex-shank power screwdrivers and impact drivers accepting 3/8 inch hex fasteners.

Installation Notes

Insert the 1/4 inch hex shank fully into the driver chuck before use. Ensure the driver is powered off or the battery is disconnected when changing bits. Inspect the magnetic tip periodically for wear or metal debris buildup that could affect fastener retention. This bit is intended for power tool use; do not use with manual drivers under high-torque conditions that exceed the bit rating.
