Product Description

OSG General Purpose Thread-Forming Taps.

Frequently Asked Questions

What is the OSG thread forming tap used for?

The OSG thread forming tap is used to create internal threads in ductile materials like aluminum, brass, and low-carbon steel without cutting. It displaces material to form threads, making it ideal for applications requiring high thread strength and no chip debris, such as automotive and aerospace manufacturing.

What are the specifications of the OSG thread forming tap 1400127305?

This OSG thread forming tap has a size of 1/4"-20 UNC, with a thread tolerance of H6 / 2B-3B. It features a plug chamfer and a TiN coated cobalt construction. The manufacturer part number is 1400127305, and it is designed for general purpose thread forming in ductile materials.

Where to buy OSG thread forming taps worldwide?

You can source OSG thread forming taps 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 times on this and other OSG tooling products.

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

To select the correct OSG thread forming tap, match the tap size and thread pitch to your hole specifications. For ductile materials like aluminum or brass, use a forming tap with appropriate coating, such as TiN for wear resistance. Ensure the thread tolerance (e.g., H6 / 2B-3B) meets your required fit class.
