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 general-purpose tapping in 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 1400125800?

The OSG Thread Forming Tap has a thread size of 1/4"-20 UNC, a thread tolerance of H7 / 2B-3B, a bottoming chamfer, and is made from cobalt high-speed steel. The manufacturer part number is 1400125800. It is designed for through-hole or blind-hole threading in ductile materials.

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

You can source the OSG Thread Forming Tap 1/4"-20 UNC (MPN 1400125800) through 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 the OSG thread forming tap based on thread size (e.g., 1/4"-20 UNC), tolerance class (H7 / 2B-3B for standard fits), chamfer type (bottoming for blind holes), and material compatibility. Cobalt taps suit harder materials. For ductile materials like aluminum, this tap provides chip-free threading. Consult OSG's technical data for specific material recommendations.
