Frequently Asked Questions

What is the OSG Thread Forming Tap #4-48 UNF used for?

The OSG Thread Forming Tap #4-48 UNF is used to create internal threads in metal without cutting, by displacing material. It is ideal for ductile materials like aluminum, brass, and low-carbon steel in general-purpose tapping applications, especially in automated or CNC machining environments.

What are the specifications of the OSG Thread Forming Tap #4-48 UNF?

This OSG tap has a #4-48 UNF thread size, H4 / 2B-3B tolerance class, plug chamfer, and is made of cobalt high-speed steel. The manufacturer part number is 1400107200. It is designed for forming threads in ductile materials without producing chips.

Where to buy OSG Thread Forming Tap #4-48 UNF worldwide?

You can source the OSG Thread Forming Tap #4-48 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 on this item.

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

Select an OSG thread forming tap based on thread size (e.g., #4-48 UNF), material type (ductile metals only), tolerance class (H4 / 2B-3B), and chamfer style (plug for general use). Cobalt construction provides heat resistance for longer tool life in production runs.
