Product Description

OSG Oversized Thread-Forming Taps.

Frequently Asked Questions

What is an OSG thread forming tap used for?

An OSG thread forming tap creates internal threads by displacing material rather than cutting it. This TiN coated cobalt tap is ideal for ductile materials like aluminum, brass, and low-carbon steel, producing stronger, burr-free threads in automotive, aerospace, and general manufacturing applications.

What are the specifications of the OSG thread forming tap 1400144405?

This OSG thread forming tap has a 1/2"-13 UNC thread size, H12 / 2B tolerance, plug chamfer, and TiN coated cobalt construction. The manufacturer part number is 1400144405. It is an oversized tap designed for producing threads with a slightly larger pitch diameter.

Where to buy OSG thread forming taps worldwide?

3G Electric supplies OSG thread forming taps worldwide. As a global industrial distributor, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time on the OSG 1400144405 tap or other thread forming tools.

How to select the correct OSG thread forming tap size?

Select the OSG tap based on thread size, pitch, and tolerance class. For a 1/2"-13 UNC thread requiring a 2B fit, use an H12 oversized tap. Ensure the tap matches the material—TiN coated cobalt suits harder materials. Always verify the hole size per OSG recommendations for proper thread formation.
