Frequently Asked Questions

What is the OSG Spiral Point Tap #8-32 UNC used for?

The OSG Spiral Point Tap #8-32 UNC is a general-purpose tap designed for through-hole threading in ferrous and non-ferrous materials. Its spiral-point design pushes chips ahead, reducing clogging and breakage. It is commonly used in automotive, aerospace, and general manufacturing for creating internal threads in steel, aluminum, and cast iron.

What are the specifications of the OSG Spiral Point Tap #8-32 UNC?

The OSG Spiral Point Tap has a #8-32 UNC thread size, H4 / 2B-3B tolerance class, 3 flutes, and a plug chamfer. The manufacturer part number is 2812900. It is designed for through-hole applications and is made from high-speed steel for durability. OSG is the OEM brand for this tap.

Where to buy the OSG Spiral Point Tap #8-32 UNC worldwide?
