CLEVELAND #2-56 UNC General Purpose Thread-Forming Tap

A CLEVELAND thread forming tap, like the #2-56 UNC model C59177, is used to create internal threads in ductile materials such as aluminum, brass, and mild steel. It displaces material rather than cutting it, producing stronger threads without chips. This makes it ideal for applications requiring high thread strength and cleanliness, common in automotive and aerospace manufacturing.

The CLEVELAND C59177 is a #2-56 UNC thread forming tap with a H2 / 2B tolerance class and a bottoming chamfer. It is made from high speed steel (HSS) for durability. This tap is designed for general purpose use in through or blind holes, forming threads in materials up to 850 °C hardness. The manufacturer part number is C59177.

To select the right CLEVELAND thread forming tap, match the tap size (e.g., #2-56 UNC) to your hole diameter and thread requirement. Choose a bottoming chamfer for blind holes or a plug chamfer for through holes. Consider material hardness; high speed steel taps suit general use. For best results, use proper lubrication and ensure the tap aligns with the hole axis to prevent breakage.
