Frequently Asked Questions

What is a CLEVELAND thread forming tap used for?

A CLEVELAND thread forming tap, like the 1/4"-20 UNC C59285, creates internal threads by displacing material rather than cutting it. This process produces stronger, burr-free threads in ductile materials such as aluminum, brass, and mild steel, making it ideal for high-production manufacturing and assembly applications.

What are the specifications of the CLEVELAND C59285 thread forming tap?

The CLEVELAND C59285 is a 1/4"-20 UNC thread forming tap with an H6 / 2B tolerance class and a bottoming chamfer. It is made from high-speed steel (HSS) and is designed for general-purpose threading in ductile materials. The manufacturer part number is C59285.

Where to buy CLEVELAND thread forming taps worldwide?

How to select the right thread forming tap for my application?

Select a thread forming tap based on material type, thread size, and chamfer style. For blind holes, use a bottoming chamfer like the CLEVELAND C59285. Ensure the tap's tolerance class (e.g., H6 / 2B) matches your required thread fit. High-speed steel taps suit general-purpose use in ductile metals.
