Milwaukee Tool 49-57-5361 M12x1.25 Hex Rethreading Die

Product Description

The MILWAUKEE TOOL 49-57-5361 is a hex rethreading die designed to restore damaged or corroded metric fine threads quickly and accurately. Part of the Hex-LOK series, this die fits a 1-inch hex drive for secure engagement with standard wrenches and ratchets. It is manufactured from carbon steel for durability under the repeated lateral and torsional loads that thread restoration work demands. The M12x1.25 metric fine thread profile makes it a targeted tool for fastener repair on automotive, mechanical, and equipment maintenance jobs where a precise thread pitch must be preserved.

This rethreading die is suited for professional technicians working in automotive service, diesel repair, industrial maintenance, and general mechanical trades. It is used to chase and restore external M12x1.25 right-hand threads on bolts, studs, and shafts without cutting new material. The compact 0.5-inch thickness allows access in moderately tight spaces. It is a single-piece, non-adjustable die intended for field repair and shop use alike.

Installation Notes

Thread restoration dies are typically used by automotive technicians, industrial mechanics, and maintenance trades. Before use, clean the damaged fastener of debris, rust, and oil to allow proper die seating. Apply cutting oil to the die and fastener to reduce friction and extend die life. Turn the die slowly in the correct thread direction, backing off periodically to clear chips, and never force the die past resistance.
