Frequently Asked Questions

What is OSG thread forming tap #12-28 UNF used for?

This OSG thread forming tap creates internal threads in ductile materials like aluminum, brass, and low-carbon steel without cutting chips. It is ideal for high-speed production in automotive, aerospace, and general manufacturing where thread strength and cleanliness are critical.

What are the specifications of OSG thread forming tap 1400125508?

The OSG thread forming tap has a #12-28 UNF thread size, H10 tolerance, plug chamfer, and TiCN coating on cobalt steel. It is designed for through-hole or blind-hole threading in materials up to 850 °C hardness, providing extended tool life and reduced torque.

Where to buy OSG thread forming tap #12-28 UNF worldwide?

3G Electric supplies and delivers the OSG thread forming tap #12-28 UNF worldwide. We handle full logistics and customs clearance, ensuring reliable sourcing for industrial buyers globally. Contact us for availability and lead time on this and other OSG tooling.

How to select the right thread forming tap for aluminum?

For aluminum, choose a thread forming tap with TiCN coating like this OSG #12-28 UNF model to reduce galling. Ensure the tap has a plug chamfer for blind holes and H10 tolerance for standard fit. Always match tap size to the pre-drilled hole diameter per manufacturer guidelines.
