Apex MDB-12 Nutsetter for 3/8" Fasteners

This Apex nutsetter fits 3/8 inch hex fasteners using a 1/4 inch hex drive insertion. It is designed for impact-rated use with a magnetised tip that holds fasteners during positioning. The tool suits mechanics and technicians who drive hex head screws or bolts in automotive, industrial or maintenance tasks. Its alloy steel construction supports repeated high-torque applications.

Impact-rated alloy steel with magnetised tip

The unfinished alloy steel body withstands impact driver forces without rounding. A magnetised tip keeps bolts or nuts seated on the socket, reducing drops in tight engine bays or overhead work. At 2-9/16 inches overall length, the nutsetter reaches recessed fasteners while staying compact enough for confined spaces. The 1/4 inch hex shank fits standard quick-change chucks and bit holders.

Single nutsetter ready for immediate use

One MDB-12 nutsetter ships in the package with no additional accessories or software. The tool arrives new and ready to insert into any 1/4 inch hex drive impact driver or drill. No calibration or setup is required; the magnetised tip functions from the first fastener. Buyers needing multiple sizes or a storage case will need to source those separately.

Questions about this item

Does the 1/4 in hex shank fit every standard impact driver?

The 1/4 in hex shank matches the universal impact-driver chuck, so it seats in any 1/4 in hex drive without an adapter.

What clearance does the 2-9/16 in overall length need in a tight engine bay?

At 2-9/16 in long, the nutsetter requires at least that much straight-line space behind the fastener, plus room for the driver body.

How do you seat the magnetized tip on a 3/8 in fastener without stripping it?

Align the 3/8 in hex socket squarely on the nut, press until the magnet holds, then start the driver slowly to avoid cam-out.
