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 1/2"-20 UNF, H11, plug chamfer, TiCN coated cobalt tap is used in ductile materials like aluminum, brass, and low-carbon steel to produce strong, burr-free threads without chips.

What are the specifications of the OSG thread forming tap 1400146108?

The OSG thread forming tap MPN 1400146108 has a thread size of 1/2"-20 UNF, H11 tolerance, plug chamfer, and TiCN coating on cobalt steel. It is an oversized tap designed for forming threads in materials up to 850 °C hardness. 3G Electric supplies this tap worldwide.

Where to buy OSG thread forming taps in worldwide?

You can source OSG thread forming taps worldwide through 3G Electric. As a global industrial distributor since 1990, we handle full logistics, customs clearance, and delivery to your facility. Contact us for availability and lead time on the OSG 1400146108 tap.

How to select the correct OSG thread forming tap size?

Select an OSG thread forming tap by matching the thread size (e.g., 1/2"-20 UNF), tolerance class (H11 for 2B fit), and chamfer type (plug for through or blind holes). Ensure the tap is oversized if required for coating or material expansion. 3G Electric can advise on application fit.
