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 in ductile materials like aluminum and steel. This 7/16"-14 UNC plug chamfer tap is ideal for high-production CNC machining where chip evacuation is problematic.

What are the specifications of the OSG 7/16"-14 UNC thread forming tap?

This OSG tap has a 7/16"-14 UNC thread size, H12 / 2B tolerance class, plug chamfer, and is made from cobalt for heat resistance. The manufacturer part number is 1400140800. It is an oversized thread-forming tap designed for precise thread fit in demanding applications.

Where to buy OSG thread forming taps worldwide?

3G Electric supplies OSG thread forming taps like the 7/16"-14 UNC model to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this cobalt tap.

How to select the correct OSG thread forming tap size?

Select an OSG thread forming tap by matching the thread size (e.g., 7/16"-14 UNC), tolerance class (H12 / 2B), and chamfer type (plug) to your application. Oversized taps like this one compensate for hole shrinkage in materials such as stainless steel. Consult OSG's technical data for optimal hole preparation.
