Cleveland C54083 Threading Tool

The Cleveland C54083 is a straight flute hand tap designed for creating internal threads in a #2-56 UNC size. Made from high speed steel with a bright uncoated finish, it features a right-hand thread direction and a taper chamfer for easier starting alignment. The overall length measures 1.75 in with a thread length of .44 in. It conforms to a class of fit 2B with a thread limit H1.

Upgrade From Worn Or Incorrect Taps

This tap replaces dull, damaged, or wrong-sized threading tools that produce loose or oversized threads. The jump is worth it when existing taps no longer hold the H1 limit required for a 2B class of fit, or when a taper start is needed to prevent cross-threading in through-holes. The 75 percent thread drill size of 1.73 mm ensures proper hole preparation for accurate results.

Suited For Precision Threading Tasks

This tool suits machinists and maintenance technicians cutting new internal threads in ferrous and non-ferrous materials where a standard H1 limit applies. It is not for buyers who need a bottoming or plug chamfer to reach the bottom of blind holes. It is also not for applications requiring a different thread limit, a coated finish for extended wear, or a larger thread size than #2-56.

Questions about this item

What drill bit diameter should I use with the #2-56 UNC tap?

Use a 1.73 mm drill bit to achieve the recommended 75 percent thread engagement.

How do I start the tap straight so the threads do not cross?

Apply steady pressure while turning the taper lead slowly; the 0.44 in thread length engages gradually to keep alignment.

When will the high-speed steel cutting edges need replacement?

Replace the tap when threads feel rough or the bright finish shows visible wear on the flutes.
