Frequently Asked Questions

What is the OSG Spiral Point Tap 2857408 used for?

The OSG Spiral Point Tap 2857408 is designed for threading blind or through holes in ferrous and non-ferrous materials. Its spiral-point geometry pushes chips forward, reducing clogging and improving thread quality in production environments.

What are the specifications of the OSG Spiral Point Tap 2857408?

This OSG tap has a 1/2"-13 UNC thread size, H11 / 2B tolerance, 3 flutes, and a plug chamfer. It is an oversized spiral-point tap, ideal for creating threads in materials requiring a slightly larger tap diameter. The MPN is 2857408.

Where to buy the OSG Spiral Point Tap 2857408 worldwide?

You can source the OSG Spiral Point Tap 2857408 through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations, ensuring reliable supply for your threading operations.

How to select the correct OSG Spiral Point Tap for my application?

Select the OSG Spiral Point Tap based on thread size (e.g., 1/2"-13 UNC), material type, and hole configuration. For blind holes, spiral-point taps push chips forward; for through holes, consider spiral-flute taps. Always match the tap tolerance (H11 / 2B) to your thread class requirements.
