Product Description

OSG General Purpose Thread-Forming Taps.

Frequently Asked Questions

What is the OSG Thread Forming Tap 3/4"-16 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 chips. It is ideal for automotive, aerospace, and general manufacturing applications requiring strong, precise threads in blind or through holes.

What are the specifications of the OSG Thread Forming Tap 3/4"-16 UNF?

This tap has a 3/4"-16 UNF thread size, H8 / 2B-3B tolerance, plug chamfer, and TiN coated cobalt construction. The manufacturer part number is 1400156405. It is designed for general purpose thread forming in materials up to 850 °C hardness.

Where to buy the OSG Thread Forming Tap 3/4"-16 UNF worldwide?

You can source the OSG Thread Forming Tap 3/4"-16 UNF 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.

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

Select based on thread size, tolerance class, and material. For ductile materials like aluminum, use a TiN coated tap like this OSG model. Ensure the tap chamfer matches your hole type—plug chamfer suits blind holes. Always match the H limit to your required thread class.
