OSG Thread Forming Tap: 1/4"-28 UNF, H6 / 2B-3B, Bottoming Chamfer

An OSG thread forming tap creates internal threads by displacing material rather than cutting it, producing stronger threads with no chips. It is ideal for ductile materials like aluminum, brass, and low-carbon steel in automotive, aerospace, and general manufacturing applications.

This OSG thread forming tap has a 1/4"-28 UNF thread size, H6 / 2B-3B tolerance class, bottoming chamfer, and is made from cobalt for heat resistance. The manufacturer part number is 1400128000. It is designed for general purpose thread forming in ductile materials.

3G Electric supplies OSG thread forming taps worldwide, handling full logistics and customs clearance for international orders. As a global industrial solutions provider, we source genuine OSG cutting tools and deliver them to your facility, ensuring compliance with local import requirements.

Select an OSG thread forming tap based on material type, thread size, and tolerance class. For ductile materials like aluminum or brass, use a bottoming chamfer tap for blind holes. Match the H6 / 2B-3B tolerance to your thread gauge requirements. Consult OSG's technical data for optimal speeds and lubrication.
