Frequently Asked Questions

What is the OSG Straight Flute Tap 5/8"-18 UNF used for?

This OSG straight flute tap is used for threading internal threads in metal components, particularly in automotive, aerospace, and general manufacturing. Its TiN coating reduces friction and extends tool life, making it suitable for ferrous and non-ferrous materials.

What are the specifications of the OSG Straight Flute Tap 5/8"-18 UNF?

This OSG tap has a 5/8"-18 UNF thread size, H3 tolerance for 2B/3B class fit, 4 flutes, plug chamfer, and TiN-coated high-speed steel construction. The manufacturer part number is 1124005, and it is designed for general-purpose hand tapping.

Where to buy the OSG Straight Flute Tap 5/8"-18 UNF worldwide?

You can source the OSG Straight Flute Tap 5/8"-18 UNF through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations, ensuring reliable supply for your operations.

How to select the correct OSG tap for UNF threads?

To select the correct OSG tap, match the thread size (e.g., 5/8"-18 UNF) and class fit (e.g., H3 for 2B/3B). Consider material type and coating: TiN suits harder materials. For hand tapping, a plug chamfer and 4-flute design provide balanced cutting and chip evacuation.
