Frequently Asked Questions

What is an OSG thread forming tap used for?

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, steel, and stainless steel in automotive, aerospace, and general manufacturing applications.

What are the specifications of the OSG 3/8"-16 UNC thread forming tap?

This OSG tap has a 3/8"-16 UNC thread size, H12 tolerance, modified bottoming chamfer, and is made from cobalt for heat resistance. The manufacturer part number is 1400135800. It is an oversized thread-forming tap designed for precise thread rolling in tough materials.

Where to buy OSG thread forming taps worldwide?

3G Electric supplies OSG thread forming taps worldwide, handling full logistics and customs clearance for global delivery. As a sourcing partner, we provide genuine OSG taps like the 3/8"-16 UNC cobalt model (MPN 1400135800) to industrial buyers across all regions.

How to select the correct OSG thread forming tap for a job?

Select an OSG thread forming tap based on material type, thread size, and tolerance class. For ductile materials, use a forming tap with H tolerance like H12. Match the chamfer type (modified bottoming for blind holes) and ensure the tap is oversized if required for thread fit.
