Frequently Asked Questions

What is the OSG Thread Forming Tap 3/8"-16 UNC used for?

This OSG thread forming tap is used to create internal threads in ductile materials such as aluminum, brass, and low-carbon steel. It is ideal for automotive, aerospace, and general manufacturing applications where chip-free threading is required. The plug chamfer design allows for versatile through-hole and blind-hole use.

What are the specifications of the OSG Thread Forming Tap 3/8"-16 UNC?

The OSG Thread Forming Tap has a 3/8"-16 UNC thread size, H4 / 2B-3B tolerance, and a plug chamfer. It is made from cobalt high-speed steel for durability. The manufacturer part number is 1400135900. This tap is designed for general purpose thread forming in materials that deform rather than cut.

Where to buy the OSG Thread Forming Tap 3/8"-16 UNC worldwide?

You can source the OSG Thread Forming Tap 3/8"-16 UNC 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. We supply genuine OSG taps to support your manufacturing operations.

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

Select an OSG thread forming tap based on material type, thread size, and tolerance. For ductile materials like aluminum or brass, use a forming tap with a plug chamfer. Ensure the tap's H limit matches your required thread class (e.g., H4 for 2B-3B). Consult OSG's technical data for optimal speeds and lubrication.
