Frequently Asked Questions

What is the OSG Spiral Point Tap 1/4"-28 UNF used for?

This OSG spiral point tap is used for threading through holes in metal, particularly in production environments. Its 2B+ oversized tolerance allows for controlled thread depth after coating or plating. The plug chamfer and two-flute design efficiently push chips forward, making it ideal for high-speed tapping in steel and aluminum.

What are the specifications of the OSG Spiral Point Tap 1590200?

The OSG Spiral Point Tap 1590200 has a thread size of 1/4"-28 UNF with a 2B+ tolerance class. It features two flutes, a plug chamfer, and is made from high-speed steel. The oversized design provides additional clearance for post-coating applications. This tap is designed for through-hole threading in industrial manufacturing.

Where to buy the OSG Spiral Point Tap 1590200 worldwide?

You can source the OSG Spiral Point Tap 1590200 through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we supply this tap to manufacturing facilities across multiple industries.

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

Select an OSG spiral point tap based on thread size, tolerance, and material. For through holes, a plug chamfer and two-flute design work well. The 2B+ oversized tolerance suits threads requiring post-plating clearance. Match the tap to your workpiece hardness; high-speed steel taps are suitable for general-purpose steel and aluminum applications.
