Frequently Asked Questions

What is the OSG Spiral Point Tap 7/16"-20 UNF used for?

This OSG spiral point tap is designed for through-hole threading in production environments. Its 3-flute, plug chamfer design pushes chips forward, reducing clogging. The 2B+ oversized tolerance suits applications requiring tighter thread fit, such as automotive or aerospace components, where precise thread class is critical.

What are the specifications of the OSG Spiral Point Tap 7/16"-20 UNF?

The OSG tap has a 7/16"-20 UNF thread size, 2B+ tolerance, 3 flutes, and a plug chamfer. It is made from high-speed steel (HSS) and carries manufacturer part number 1594200. The 2B+ designation indicates an oversized pitch diameter for achieving a tighter thread fit in demanding applications.

Where to buy the OSG Spiral Point Tap 7/16"-20 UNF worldwide?

3G Electric supplies the OSG 1594200 spiral point tap worldwide. As a global industrial distributor, we handle full logistics, customs clearance, and delivery to your facility. Contact us for availability and lead time; we source and deliver this tap to support your threading operations anywhere.

How to select the correct OSG spiral point tap for through-hole threading?

Select based on thread size, pitch, and hole type. For through holes, a spiral point tap pushes chips ahead, reducing breakage. The 2B+ oversized class provides tighter fit for critical threads. Ensure the tap material (HSS) matches workpiece hardness. OSG taps like the 1594200 are engineered for consistent performance in production runs.
