Frequently Asked Questions

What is the OSG Thread Forming Tap 2866400 used for?

The OSG Thread Forming Tap 2866400 is used to create internal threads in ductile materials like aluminum, brass, and low-carbon steel. It is ideal for automotive, aerospace, and general manufacturing applications where chip-free threading and strong thread profiles are required.

What are the specifications of the OSG Thread Forming Tap 2866400?

This OSG tap has a thread size of 5/16"-24 UNF, a 2B class of fit, and a bottoming chamfer. It is made from high-speed steel (HSS) and is designed for general-purpose thread forming. The manufacturer part number is 2866400.

Where to buy the OSG Thread Forming Tap 2866400 worldwide?

You can source the OSG Thread Forming Tap 2866400 through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations, ensuring you receive the correct tap for your threading application.

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

Select the OSG thread forming tap based on material, thread size, and chamfer type. For through holes, use a plug or bottoming chamfer; for blind holes, a bottoming chamfer is best. Ensure the tap matches the required UNF thread class (e.g., 2B) and is suitable for your workpiece hardness.
