Frequently Asked Questions

What is OSG spiral point tap used for?

OSG spiral point taps are designed for through-hole threading in production environments. The spiral point pushes chips ahead, reducing clogging and enabling faster tapping in materials like steel and aluminum. This #4-40 UNC, 3B, 2 flute, plug chamfer tap is ideal for precision internal threads in machining and assembly operations.

What are the specifications of OSG spiral point tap #4-40 UNC?

This OSG spiral point tap has a #4-40 UNC thread size, 3B class fit, 2 flutes, plug chamfer, and is made from high speed steel. The 3B tolerance ensures a snug fit for critical applications. Manufacturer part number is 2880000. It is a general purpose tap for through-hole threading.

Where to buy OSG spiral point tap #4-40 UNC worldwide?

3G Electric supplies OSG spiral point taps worldwide. As a global industrial solutions provider, we handle full logistics, customs clearance, and delivery to your facility. Contact us to source this #4-40 UNC, 3B, 2 flute tap (MPN 2880000) for your production needs.

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

For through holes, choose a spiral point tap like this OSG #4-40 UNC model. The spiral point pushes chips forward, preventing chip packing. Ensure the tap matches your thread size (UNC), class fit (3B for tight tolerance), and material (high speed steel for general use). Plug chamfer is standard for most applications.
