Frequently Asked Questions

What is OSG Thread Forming Tap #12-28 UNF used for?

This OSG thread forming tap creates internal threads in ductile materials like aluminum, brass, and low-carbon steel without cutting chips. It is ideal for automotive, aerospace, and general manufacturing applications requiring strong, burr-free threads in blind or through holes.

What are the specifications of OSG Thread Forming Tap 1400124900?

The OSG thread forming tap has a #12-28 UNF thread size, H4 / 2B-3B tolerance, plug chamfer, and is made from cobalt high-speed steel. The manufacturer part number is 1400124900. It is designed for general purpose thread forming in a range of materials.

Where to buy OSG Thread Forming Tap #12-28 UNF worldwide?

3G Electric supplies and delivers the OSG Thread Forming Tap #12-28 UNF (MPN 1400124900) worldwide. As a global industrial solutions provider, we handle full logistics and customs clearance to ensure your order arrives at your facility, wherever you are located.

How to select the right thread forming tap for aluminum?

For aluminum, choose a thread forming tap with a polished flute and appropriate coating to reduce friction and galling. The OSG cobalt tap with H4 / 2B-3B tolerance works well. Ensure the tap size matches your hole diameter and thread class, and use proper lubrication during forming.
