Frequently Asked Questions

What is the OSG thread forming tap used for?

The OSG thread forming tap is used to create internal threads in ductile materials such as aluminum, brass, and low-carbon steel. It is ideal for automotive, aerospace, and general manufacturing applications where chip-free threading and stronger thread profiles are required.

What are the specifications of the OSG thread forming tap?

This OSG tap has a 1/2"-20 UNF thread size, H5 / 2B-3B tolerance, plug chamfer, and black oxide cobalt finish. The manufacturer part number is 1400145501. It is designed for general purpose thread forming in materials that produce continuous chips.

Where to buy OSG thread forming taps worldwide?

You can source OSG thread forming taps worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time on this and other OSG tooling.

How to select the correct OSG thread forming tap?

Select the tap based on thread size, pitch, and material. For 1/2"-20 UNF threads in ductile materials, use a plug chamfer tap with H5 tolerance. Ensure the hole size matches the tap's recommended pre-drill diameter. OSG taps are designed for consistent thread quality and long tool life.
