Frequently Asked Questions

What is the OSG Thread Forming Tap 9/16"-18 UNF used for?

This OSG thread forming tap is used to create internal threads in metal without cutting, by displacing material. It is ideal for ductile materials like aluminum, steel, and stainless steel, commonly in automotive and aerospace applications. The H12 tolerance ensures precise thread fit for high-strength joints.

What are the specifications of the OSG Thread Forming Tap 9/16"-18 UNF?

The OSG thread forming tap has a size of 9/16"-18 UNF, with an H12 tolerance class. It features a plug chamfer and is made from cobalt high-speed steel for durability. The manufacturer part number is 1400149800. This oversized tap is designed for forming threads in tough materials.

Where to buy the OSG Thread Forming Tap 9/16"-18 UNF worldwide?

You can source the OSG Thread Forming Tap 9/16"-18 UNF through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time on this OSG tap.

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

Select the OSG thread forming tap based on thread size, pitch, and tolerance class (e.g., H12 for tight fit). Ensure the tap material (cobalt) matches your workpiece hardness. Use a plug chamfer for through holes. For oversized taps, verify hole size per OSG guidelines to avoid breakage.
