Frequently Asked Questions

What is OSG spiral point tap #5-40 UNC used for?

The OSG spiral point tap #5-40 UNC is designed for through-hole threading in ferrous and non-ferrous materials. Its spiral point pushes chips forward, preventing clogging and enabling faster production. Common applications include automotive, aerospace, and general machining where clean, accurate threads are required.

What are the specifications of OSG spiral point tap 2807001?

The OSG spiral point tap 2807001 has a #5-40 UNC thread size, H2 / 2B-3B tolerance class, 2 flutes, and a plug chamfer. It is a general-purpose tap for through-hole threading. These specs ensure precise thread fit and compatibility with standard UNC fasteners in industrial machining operations.

Where to buy OSG spiral point tap #5-40 UNC worldwide?

3G Electric supplies the OSG spiral point tap #5-40 UNC (MPN 2807001) to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. As a global industrial solutions provider, we source genuine OSG taps and support procurement teams across 14 departments with reliable service.

How to select the correct OSG spiral point tap for my application?

Select the OSG spiral point tap based on thread size, pitch, and material. For #5-40 UNC, use a plug chamfer for through-holes. Match the H tolerance (e.g., H2) to your required thread class (2B-3B). Consult OSG’s technical data for speed and feed recommendations. 3G Electric can help verify fit for your specific job.
