Frequently Asked Questions

What is a CLEVELAND thread forming tap used for?

A CLEVELAND thread forming tap creates internal threads by displacing material rather than cutting it. It is ideal for ductile materials like aluminum, brass, and low-carbon steel, producing stronger, burr-free threads in through or blind holes.

What are the specifications of the CLEVELAND C59290 thread forming tap?

The CLEVELAND C59290 is a 1/4"-28 UNF thread forming tap with H4 / 2B tolerance, bottoming chamfer, and high-speed steel construction. It is designed for precise thread forming in applications requiring a 2B fit class.

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

Select a CLEVELAND thread forming tap based on thread size (e.g., 1/4"-28 UNF), material type, and hole configuration. For blind holes, use a bottoming chamfer like the C59290. Ensure the tap tolerance (H4) matches the required thread class (2B).
