Hex Rethreading Die for 1-3/8 Inch UNF Bolts

This Cleveland Golf C65631 die restores damaged external threads on bolts measuring 1-3/8 inches with 12 threads per inch. The carbon steel construction provides durability for workshop use. A hexagonal profile allows the die to be turned with a standard wrench or socket.

Suited for maintenance

Mechanics and fabricators who need to clean up existing 1-3/8-12 UNF bolt threads will find this tool appropriate. It is not intended for cutting new threads on unthreaded rod or for metric, NPT, or finer-pitch fasteners. Users requiring adjustable or split dies should select a different type.

12 threads per inch UNF pitch

The fixed 12 TPI pitch matches only Unified National Fine threads of that specific count. Verify the bolt specification before purchase because the die cannot accommodate other pitches or diameters. The 2.1375 inch hex size determines the wrench required for operation.

Questions about this item

How can I confirm the die is cutting threads correctly after setup?

After setup, the die should produce a clean 1-3/8-12 UNF right-hand thread on the bolt with a bright machined finish and no torn or cross-threaded sections.

What comes in the box with the Cleveland Golf C65631 and what must I supply separately?

The package contains the solid carbon steel hex rethreading die only; you must provide a compatible hex die stock or wrench and cutting lubricant.

Which version of the C65631 should I choose for a 1-3/8-12 UNF bolt?

The C65631 is a single specification — 1-3/8-12 UNF right-hand thread, 2.1375 in hex size, 1 in thickness — so select this model when those exact dimensions match your bolt.
