Frequently Asked Questions

What is an OSG thread forming tap used for?

An OSG thread forming tap creates internal threads in ductile materials like aluminum, brass, and steel without cutting. It displaces material to form threads, producing stronger, burr-free threads ideal for automotive, aerospace, and general manufacturing applications.

What are the specifications of the OSG #4-40 UNC thread forming tap?

This OSG tap is #4-40 UNC size, with an H7 tolerance, bottoming chamfer, and black oxide cobalt finish. The manufacturer part number is 1400157401. It is designed for general purpose thread forming in materials up to 850 °C hardness.

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 #4-40 UNC tap or other 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, chamfer type, and material. For #4-40 UNC, use a bottoming chamfer for blind holes. Ensure the tap's H7 tolerance matches your thread class. Consult OSG's technical data for optimal speeds and lubrication.
