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 5/8"-18 UNF tap with H12 / 2B tolerance is ideal for ductile materials like aluminum, brass, and low-carbon steel in automotive and aerospace applications.

What are the specifications of the OSG 5/8"-18 UNF thread forming tap?

This OSG tap has a 5/8"-18 UNF thread size, H12 / 2B class of fit, plug chamfer, and black oxide cobalt finish. The manufacturer part number is 1400153401. It is an oversized thread-forming tap designed for precise internal threading in ductile materials.

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 location. Contact us for availability and lead time on this 5/8"-18 UNF tap.

How to select the correct OSG thread forming tap size?

Select the tap based on thread size, class of fit, and material. For this OSG tap, the 5/8"-18 UNF size and H12 / 2B tolerance suit applications requiring precise thread fit. Ensure the hole diameter matches the tap's specifications for proper thread formation without breakage.
