Product Description

OSG General Purpose Thread-Forming Taps.

Frequently Asked Questions

What is the OSG Thread Forming Tap 2866200 used for?

The OSG Thread Forming Tap 2866200 is used to create internal threads in ductile materials like aluminum, brass, and low-carbon steel. It forms threads by displacing material rather than cutting, producing stronger, burr-free threads. Common applications include automotive, aerospace, and general manufacturing where thread integrity is critical.

What are the specifications of the OSG Thread Forming Tap 2866200?

The OSG Thread Forming Tap has a thread size of 5/16"-18 UNC, 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 2866200, and it is suitable for through or blind holes.

Where to buy the OSG Thread Forming Tap 2866200 worldwide?

You can source the OSG Thread Forming Tap 2866200 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 provide reliable sourcing for this OSG tap.

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

To select the correct OSG Thread Forming Tap, match the thread size (5/16"-18 UNC), class of fit (2B), and chamfer type (bottoming for blind holes) to your workpiece material. For ductile materials like aluminum or brass, this HSS tap works well. Ensure proper lubrication and hole size per OSG recommendations for optimal thread formation.
