Frequently Asked Questions

What is the OSG spiral flute tap 3/4"-10 UNC used for?

The OSG spiral flute tap is used for threading blind holes in ferrous and non-ferrous materials. Its spiral flute design evacuates chips upward, preventing clogging in deep or blind-hole applications. Common uses include automotive, aerospace, and general manufacturing where precise UNC threads are required.

What are the specifications of the OSG spiral flute tap 3/4"-10 UNC?

This OSG tap has a 3/4"-10 UNC thread size, H3 / 2B-3B tolerance, 4 flutes, and a bottoming chamfer. It is made of high-speed steel (HSS) and is designed for general-purpose threading. The manufacturer part number is 1433700.

How to select the correct OSG spiral flute tap for a job?

Select the tap based on thread size, pitch, and material. For blind holes, use a spiral flute tap with a bottoming chamfer like this OSG model. Match the H limit (e.g., H3) to the required thread class (2B or 3B). Ensure the tap material suits the workpiece—HSS works for most metals.
