Frequently Asked Questions

What is the OSG #8-32 UNC spiral point tap used for?

The OSG #8-32 UNC spiral point tap is designed for through-hole threading in ferrous and non-ferrous materials. Its spiral point design pushes chips ahead, reducing chip clogging. The 2B+ oversized tolerance allows for controlled thread fit after coating or plating, common in automotive and general manufacturing.

What are the specifications of the OSG 1592801 tap?

The OSG 1592801 is a #8-32 UNC spiral point tap with a 2B+ thread class, 2 flutes, plug chamfer, and black oxide high-speed steel construction. It is an oversized tap for applications requiring additional clearance after plating. The 2B+ designation ensures a slightly larger pitch diameter than standard 2B.

How to select the correct OSG spiral point tap for through holes?

For through holes, choose a spiral point tap like the OSG #8-32 UNC with plug chamfer to push chips forward. Verify thread size, pitch, and class (e.g., 2B+ for oversized fit). Match tap material to workpiece: black oxide HSS suits general steel. Confirm flute count and coating for chip evacuation and tool life.
