Frequently Asked Questions

What is the OSG Thread Forming Tap 1/4"-20 UNC used for?

This 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 high thread strength are required.

What are the specifications of the OSG Thread Forming Tap 1400127508?

The OSG Thread Forming Tap has a thread size of 1/4"-20 UNC, a thread limit of H8 / 2B, a plug chamfer, and a TiCN coating on cobalt steel. The manufacturer part number is 1400127508. It is designed for general purpose thread forming in ductile materials.

Where to buy OSG Thread Forming Tap 1/4"-20 UNC worldwide?

You can source the OSG Thread Forming Tap 1/4"-20 UNC from 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time.

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

Select an OSG thread forming tap based on thread size, pitch, and material. For ductile materials like aluminum or brass, use a forming tap with a TiCN coating for longer tool life. Ensure the thread limit (e.g., H8 / 2B) matches your required tolerance. Consult OSG's technical data for optimal speeds and lubrication.
