Frequently Asked Questions

What is the OSG Thread Forming Tap 2866005 used for?

The OSG Thread Forming Tap 2866005 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 TiN coating reduces friction and extends tool life.

What are the specifications of the OSG Thread Forming Tap 2866005?

The OSG Thread Forming Tap 2866005 has a thread size of 1/4"-28 UNF, a 2B class of fit, and a bottoming chamfer. It is made from TiN coated high-speed steel. The manufacturer part number is 2866005. This tap is designed for through-hole or blind-hole threading in softer materials.

Where to buy the OSG Thread Forming Tap 2866005 worldwide?

You can source the OSG Thread Forming Tap 2866005 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. We supply genuine OSG taps for industrial threading needs.

How to select the correct OSG Thread Forming Tap for my application?

Select the OSG Thread Forming Tap based on thread size, pitch, and material. For 1/4"-28 UNF threads in aluminum or steel, use a bottoming chamfer tap for blind holes. Ensure the tap drill size matches the thread specification. OSG taps require proper lubrication and rigid tapping equipment for best results.
