5/16" Magnetic Nutsetter Bit

This 5/16 inch magnetic hex nutsetter bit fits drills and drivers that accept a 1/4 inch shank. It is designed for general-purpose fastening tasks around the house, shop or garage. The magnetic head holds hex fasteners securely during installation or removal.

Magnetic Hex Head Benefit

The magnetic hex head keeps nuts and bolts in place on the bit, reducing drops and speeding up repetitive fastening work. This feature is especially useful when working in tight spaces or overhead where retrieving fallen hardware is difficult.

1-7/8" Length Capacity

At 1-7/8 inches long, the bit reaches recessed fasteners while remaining compact enough for confined areas. It handles common 5/16 inch hex heads on light-duty automotive, maintenance and assembly jobs but is not suited for high-torque impact applications or larger fastener sizes.

Questions about this item

When should the magnetic tip on the 5/16" nutsetter be replaced?

Replace the bit when the magnet no longer holds the fastener securely or the hex corners show visible rounding that causes slippage during use.

What limits continuous use of the 1/4" shank nutsetter?

The 1/4" shank will transmit torque until it reaches its shear limit; excessive force on stubborn fasteners can twist or snap the shank before the magnetic tip fails.

Does the 1-7/8" length nutsetter get hot during all-day drilling?

The bit itself generates minimal heat; any warmth comes from the drill motor and friction in the fastener, not from the nutsetter during extended sessions.
