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 without cutting, which eliminates chips and produces stronger threads. It is ideal for ductile materials such as aluminum, mild steel, and stainless steel in general manufacturing and automotive applications.

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

This tap has a 5/16"-18 UNC thread size, a modified bottoming chamfer, and is made from cobalt. It is rated H3 / 2B-3B for thread fit. The manufacturer part number is 1400130500. It is designed for through-hole or blind-hole thread forming in production environments.

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

You can source the OSG Thread Forming Tap 5/16"-18 UNC (MPN 1400130500) from 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.

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

Select a thread forming tap based on material type, thread size, and chamfer style. For blind holes, use a modified bottoming chamfer as on this OSG tap. Ensure the tap's H limit (H3) matches the required thread class (2B-3B). Cobalt taps suit harder materials and provide longer tool life.
