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 environments where chip evacuation is problematic, such as automotive and aerospace manufacturing.

What are the specifications of OSG thread forming tap 1400125400?

This OSG tap is #12-28 UNF size with an H9 tolerance class, plug chamfer, and cobalt construction. The H9 tolerance ensures precise thread fit for general-purpose forming in materials up to 850 °C hardness. It is designed for through-hole or blind-hole applications.

Where to buy OSG thread forming tap 1400125400 worldwide?

3G Electric supplies and delivers this OSG thread forming tap worldwide. As a global industrial sourcing partner, we handle full logistics and customs clearance to ensure your order reaches any international destination. Contact us for availability and lead time.

How to select the right thread forming tap for aluminum?

For aluminum, choose a thread forming tap with a polished flute and cobalt or HSS-E material to reduce friction. The OSG #12-28 UNF with H9 tolerance is suitable for aluminum alloys. Ensure proper lubrication and spindle speed per manufacturer guidelines to avoid galling.
