Frequently Asked Questions

What is the OSG Thread Forming Tap 5/16"-18 UNC used for?

This OSG thread forming tap is used to create internal threads in metal workpieces without cutting material. It is ideal for general purpose threading in ductile materials such as steel, aluminum, and brass, commonly found in automotive, aerospace, and industrial manufacturing applications.

What are the specifications of the OSG Thread Forming Tap 5/16"-18 UNC?

The OSG thread forming tap has a size of 5/16"-18 UNC, with a thread tolerance of H8 / 2B. It features a bottoming chamfer and a black oxide cobalt finish. The manufacturer part number is 1400130201. This tap is designed for forming threads in ductile materials.

Where to buy the OSG Thread Forming Tap 5/16"-18 UNC worldwide?

You can source the OSG Thread Forming Tap 5/16"-18 UNC worldwide through 3G Electric. As a global industrial equipment distributor, 3G Electric handles full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time.

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

To select the correct OSG thread forming tap, match the tap size and thread pitch to your workpiece hole. For 5/16"-18 UNC, ensure the material is ductile (e.g., aluminum or low-carbon steel). The H8 / 2B tolerance indicates a medium fit class. Use a bottoming chamfer for blind holes. Consult OSG's technical data for optimal speeds and lubrication.
