Frequently Asked Questions

What is the OSG Thread Forming Tap #6-40 UNF used for?

This OSG thread forming tap is used to create internal threads in ductile materials like aluminum, brass, and low-carbon steel without cutting. It is ideal for applications requiring strong, burr-free threads in automotive, aerospace, and general manufacturing. The modified bottoming chamfer allows threading close to the bottom of blind holes.

What are the specifications of the OSG Thread Forming Tap #6-40 UNF?

This tap has a #6-40 UNF thread size, H9 tolerance class, and a modified bottoming chamfer. It is made from cobalt high-speed steel for durability. The manufacturer part number is 1400112800. It is designed for general-purpose thread forming in materials that displace rather than cut.

Where to buy the OSG Thread Forming Tap #6-40 UNF worldwide?

You can source the OSG Thread Forming Tap #6-40 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 time; we provide reliable sourcing for this OSG tap.

How to select the correct OSG thread forming tap for your application?

Select based on thread size, tolerance class, and material. For #6-40 UNF threads, use this H9 tap for ductile materials like aluminum or brass. Ensure the hole size matches the tap's recommended pre-drill diameter. For blind holes, a modified bottoming chamfer allows threading closer to the bottom. Consult OSG's technical data for optimal results.
