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 such as aluminum, brass, and low-carbon steel. It is ideal for applications requiring strong, chip-free threads in automotive, aerospace, and general manufacturing. The bottoming chamfer allows threading close to the bottom of blind holes.

What are the specifications of the OSG thread forming tap 1/4"-28 UNF?

The OSG thread forming tap has a 1/4"-28 UNF thread size with an H7 / 2B tolerance class. It features a bottoming chamfer and is made from cobalt high-speed steel for durability. The manufacturer part number is 1400128100. This tap is designed for general purpose thread forming in a variety of materials.

Where to buy OSG thread forming taps in worldwide?

You can source OSG thread forming taps worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time on this OSG tap. We supply genuine OSG cutting tools to customers across industries.

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

Select an OSG thread forming tap based on thread size, pitch, and material. For 1/4"-28 UNF threads in ductile materials, this cobalt tap with bottoming chamfer is suitable. Ensure the tap matches the required tolerance class (H7 / 2B). For harder materials or through holes, consider a different chamfer type. Consult OSG's technical guides for specific recommendations.
