Frequently Asked Questions

What is the OSG Straight Flute Tap 5/8"-11 UNC used for?

This OSG tap is used for cutting internal threads in metal components. The 5/8"-11 UNC size suits general-purpose threading in maintenance, repair, and production environments. Its bottoming chamfer allows threading close to the bottom of blind holes, while the 4-flute design aids chip evacuation.

What are the specifications of the OSG Straight Flute Tap 5/8"-11 UNC?

This OSG tap has a 5/8"-11 UNC thread size, 2B+ tolerance class, 4 flutes, and a bottoming chamfer. It is made from high-speed steel (HSS) for durability. The manufacturer part number is 1125700. It is designed for hand tapping operations in ferrous and non-ferrous materials.

Where to buy the OSG Straight Flute Tap 5/8"-11 UNC worldwide?

How to select the correct OSG tap for threading?

Select a tap based on thread size, pitch, and hole type. For blind holes, use a bottoming chamfer tap like this OSG model. For through holes, a plug or taper chamfer works. Match the tap material to the workpiece: high-speed steel suits general metals. Always verify the thread class (e.g., 2B+) for fit.
