OSG Thread Forming Tap: 1/4"-28 UNF, H5 / 2B-3B, Modified Bottoming Chamfer

The OSG thread forming tap 1400128500 is used to create internal threads in ductile materials like aluminum, brass, and low-carbon steel. It forms threads by displacing material rather than cutting, producing stronger threads with no chips. Common applications include automotive, aerospace, and general manufacturing where thread integrity is critical.

This OSG thread forming tap has a 1/4"-28 UNF thread size, H5 tolerance for 2B-3B class fit, and a modified bottoming chamfer. It is made from cobalt high-speed steel for heat resistance and wear durability. The manufacturer part number is 1400128500, and it is designed for general-purpose thread forming in production environments.

Select the OSG thread forming tap based on thread size (e.g., 1/4"-28 UNF), material type, and required thread class (2B-3B). Use a modified bottoming chamfer for blind holes. Cobalt steel taps suit harder materials. Ensure hole size matches tap drill diameter for proper thread formation. Consult OSG's technical data for feed and speed recommendations.
