Milwaukee Tool 49-57-5358 Hex Rethreading Die M12x1.75

Product Description

The MILWAUKEE TOOL 49-57-5358 is a hex rethreading die designed to restore damaged or corroded external metric threads without requiring a full tap-and-die set. Part of the Hex-LOK series, this die accepts a 1.0 inch hex driver or wrench for fast, controlled engagement. It is machined from carbon steel for durability in field and shop use. The die cuts a right-hand M12x1.75 metric coarse thread profile and is fixed at a 0.5 inch thickness, making it a compact, single-purpose tool suited for bolt and fastener thread repair across mechanical, plumbing, and electrical trade applications.

This rethreading die is used wherever M12x1.75 metric coarse threads need to be restored on bolts, studs, or threaded rod. It is well suited for automotive, HVAC equipment, and industrial maintenance work where fasteners are exposed to corrosion, impact damage, or cross-threading. The Hex-LOK hex shank design allows the die to be driven with a standard wrench or held in a rethreading die stock. It is sold individually and intended for professional tradespeople who perform routine fastener maintenance in the field.

Installation Notes

Rethreading dies are typically used by mechanical, HVAC, and plumbing technicians during maintenance and repair work. Before use, ensure the fastener is de-tensioned and free of the joint where possible. Apply cutting oil to the die and fastener to reduce friction and improve thread finish. Drive the die slowly in the correct direction, backing off periodically to clear debris.
