Frequently Asked Questions

What is the OSG spiral point tap #4-48 UNF used for?

The OSG spiral point tap #4-48 UNF is used for threading holes in production machining, particularly for through-hole applications. Its spiral-point design pushes chips ahead, reducing clogging in materials like steel and aluminum. It is common in automotive, aerospace, and general manufacturing where precise UNF threads are required.

What are the specifications of the OSG spiral point tap #4-48 UNF?

The OSG spiral point tap #4-48 UNF has a thread size of #4-48 UNF, a H2 / 2B-3B tolerance class, 2 flutes, and a plug chamfer. The manufacturer part number is 2816508. It is designed for general-purpose threading in through-hole applications, providing accurate thread formation in various materials.

Where to buy OSG spiral point tap #4-48 UNF worldwide?

You can source the OSG spiral point tap #4-48 UNF 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 times; we supply genuine OSG taps to support your production needs.

How to select the correct OSG spiral point tap for a job?

To select the correct OSG spiral point tap, match the thread size (e.g., #4-48 UNF) and tolerance class (H2 / 2B-3B) to your hole requirements. Use spiral-point taps for through-holes; they push chips forward. Consider material hardness and tap coating for longer life. Consult OSG's technical data for optimal feed and speed rates.
