Frequently Asked Questions

What is the OSG Thread Forming Tap 1/4"-28 UNF used for?

This OSG thread forming tap is used to create internal threads in ductile materials like aluminum, brass, and low-carbon steel without cutting. It is ideal for applications requiring strong, burr-free threads in automotive, aerospace, and general manufacturing. The TiCN coating extends tool life in abrasive materials.

What are the specifications of the OSG Thread Forming Tap 33WZ24?

The OSG Thread Forming Tap has a 1/4"-28 UNF thread size, H11 tolerance, modified bottoming chamfer, and TiCN coated cobalt construction. The manufacturer part number is 1400159208. It is designed for forming threads in ductile materials and is suitable for through or blind holes.

Where to buy the OSG Thread Forming Tap 33WZ24 worldwide?

You can source the OSG Thread Forming Tap 33WZ24 from 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 tooling for manufacturing operations.

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

Select the OSG thread forming tap based on material type, thread size, and hole condition. For ductile materials like aluminum or steel, use a forming tap with TiCN coating for wear resistance. The H11 tolerance ensures precise thread fit. Ensure the tap's chamfer matches your hole type: modified bottoming for blind holes.
