OSG Oversized Thread-Forming Taps.

Frequently Asked Questions

What is an OSG thread forming tap used for?

An OSG thread forming tap creates internal threads by displacing material rather than cutting it. This 5/8"-18 UNF tap is ideal for ductile materials like aluminum, steel, and stainless steel, producing stronger, burr-free threads in automotive, aerospace, and general manufacturing applications.

What are the specifications of the OSG thread forming tap 5/8"-18 UNF?

This OSG tap has a 5/8"-18 UNF thread size, H12 / 2B tolerance, plug chamfer, and TiCN coating on cobalt steel. The manufacturer part number is 1400153408. It is an oversized thread-forming tap designed for precise thread forming in demanding industrial environments.

Where to buy OSG thread forming taps worldwide?

3G Electric supplies OSG thread forming taps worldwide. As a global industrial distributor, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time on this 5/8"-18 UNF tap (MPN 1400153408).

How to select the correct OSG thread forming tap size?

Select the tap based on thread size, pitch, and tolerance class. For this OSG tap, use a 5/8"-18 UNF thread with H12 / 2B tolerance. Ensure the material is ductile (e.g., aluminum, steel) and choose TiCN coating for wear resistance. Always match the tap to the hole size and application requirements.
