Frequently Asked Questions

What is OSG straight flute tap 1/2-20 UNF used for?

This OSG straight flute tap is designed for threading aluminum and non-ferrous materials. Its V coated powdered metal construction and bottoming chamfer produce precise internal threads in blind holes. It is commonly used in automotive, aerospace, and general machining applications where UNF thread accuracy is critical.

What are the specifications of OSG tap 1005201608?

The OSG tap 1005201608 is a 1/2"-20 UNF straight flute tap with H3 / 2B-3B tolerance, 4 flutes, and a bottoming chamfer. It is made of V coated powdered metal for wear resistance. This tap is suitable for threading aluminum and other soft materials in machine tapping operations.

Where to buy OSG taps in worldwide?

3G Electric supplies OSG taps like the 1/2"-20 UNF straight flute tap to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this or any OSG cutting tool you need for your production line.

How to select the right tap for aluminum threading?

For aluminum threading, choose a tap with a polished flute and coating to reduce chip adhesion. A bottoming chamfer is ideal for blind holes, while a plug chamfer suits through holes. OSG's V coated powdered metal taps provide good wear life in aluminum. Match thread size and tolerance (e.g., H3 / 2B-3B) to your application.
