Frequently Asked Questions

What is the OSG Spiral Point Tap 1591600 used for?

The OSG Spiral Point Tap 1591600 is used for threading through-holes in metal, primarily in automotive, aerospace, and general manufacturing. Its spiral-point design pushes chips forward, reducing clogging and improving thread quality in production environments.

What are the specifications of the OSG Spiral Point Tap 1591600?

This OSG tap has a 3/8"-16 UNC thread size, 2B+ class of fit, 3 flutes, and a plug chamfer. It is made of high-speed steel (HSS) and is an oversized spiral-point tap designed for through-hole threading. The manufacturer part number is 1591600.

Where to buy the OSG Spiral Point Tap 1591600 worldwide?

You can source the OSG Spiral Point Tap 1591600 through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations, ensuring you receive the correct tap for your threading application.

How to select the correct OSG Spiral Point Tap for through-holes?

Select an OSG spiral point tap like the 1591600 for through-holes to push chips ahead and prevent packing. Match the thread size (3/8"-16 UNC), class of fit (2B+), and material (HSS) to your workpiece. For oversized threads, confirm the tap is marked oversized to achieve proper fit.
