Frequently Asked Questions

What is OSG thread forming tap 1/4"-20 UNC used for?

This OSG thread forming tap creates internal threads in ductile materials like aluminum, steel, and brass 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 1/4"-20 UNC?

This OSG tap has a 1/4"-20 UNC thread size, H8 / 2B tolerance class, modified bottoming chamfer, and TiCN coated cobalt construction. The manufacturer part number is 1400126608. It is designed for general purpose thread forming in through or blind holes.

Where to buy OSG thread forming tap 1/4"-20 UNC worldwide?

3G Electric supplies and delivers this OSG thread forming tap worldwide. As a global industrial solutions provider, we handle full logistics and customs clearance to ensure your order arrives at your facility, no matter the location.

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

Select based on material, thread size, and tolerance. For ductile materials like aluminum or low-carbon steel, a TiCN coated cobalt tap with H8 / 2B tolerance works well. Ensure the chamfer type matches your hole condition: modified bottoming for blind holes, plug for through holes.
