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. It is ideal for ductile materials like aluminum, steel, and stainless steel, producing stronger, burr-free threads in applications such as automotive, aerospace, and general manufacturing.

What are the specifications of the OSG 7/16"-20 UNF thread forming tap?

This OSG tap has a 7/16"-20 UNF thread size, H4 / 2B-3B tolerance, modified bottoming chamfer, and black oxide cobalt finish. The manufacturer part number is 1400140901. It is designed for general purpose thread forming in a range of materials.

Where to buy OSG thread forming taps worldwide?

3G Electric supplies OSG thread forming taps worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact us for availability and lead time on this 7/16"-20 UNF tap or any OSG tooling needs.

How to select the right OSG thread forming tap for my application?

Select an OSG thread forming tap based on thread size, pitch, tolerance class (e.g., H4 / 2B-3B), chamfer type, and material. For blind holes, use a modified bottoming chamfer. Ensure the tap matches your workpiece material and machine capability for optimal thread quality and tool life.
