OSG Thread Forming Tap: 1/2"-20 UNF, H12, Modified Bottoming Chamfer

An OSG thread forming tap creates internal threads by displacing material rather than cutting it. This 1/2"-20 UNF tap is ideal for ductile materials like aluminum, steel, and stainless steel, producing stronger, burr-free threads in automotive, aerospace, and general manufacturing applications.

This OSG thread forming tap has a 1/2"-20 UNF thread size, H12 tolerance, modified bottoming chamfer, and is made from cobalt high-speed steel. The manufacturer part number is 1400145300. It is designed for forming threads in ductile materials with precise dimensional control.

Select an OSG thread forming tap based on thread size, tolerance class, and material. For 1/2"-20 UNF threads in aluminum or steel, use a cobalt tap with H12 tolerance. Ensure the chamfer type matches your hole depth—modified bottoming is for blind holes. Always match tap to material hardness for optimal thread quality.
