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 3/8"-16 UNC tap is used in ductile materials like aluminum, brass, and low-carbon steel to produce stronger, burr-free threads without chips.

What are the specifications of the OSG 3/8"-16 UNC thread forming tap?

This OSG tap has a 3/8"-16 UNC thread size, H11 / 2B tolerance, plug chamfer, and black oxide cobalt finish. The manufacturer part number is 1400136601. It is designed for through-hole or blind-hole thread forming in materials up to 850 °C hardness.

Where to buy OSG thread forming taps worldwide?

You can source OSG thread forming taps worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your site. Contact us for availability and lead time on this MPN 1400136601.

How to select the correct OSG thread forming tap size?

Select the tap based on thread size, pitch, and tolerance class. For a 3/8"-16 UNC thread, use a tap with H11 / 2B tolerance. Ensure the material is suitable for forming (e.g., aluminum, brass). OSG taps require proper lubrication and a pre-drilled hole at the recommended diameter.
