Frequently Asked Questions

What is the OSG Thread Forming Tap 1400138305 used for?

The OSG Thread Forming Tap 1400138305 is used to create internal threads in ductile materials such as steel, stainless steel, and aluminum. It is ideal for automotive, aerospace, and general manufacturing applications where strong, chip-free threads are required. This tap cold-forms threads rather than cutting them, improving thread strength and surface finish.

What are the specifications of the OSG Thread Forming Tap 1400138305?

The OSG Thread Forming Tap has a thread size of 3/8"-24 UNF, with an H5 tolerance class for 2B-3B fit. It features a plug chamfer and a TiN (titanium nitride) coating on cobalt steel. The manufacturer part number is 1400138305. This tap is designed for general-purpose thread forming in a variety of materials.

Where to buy the OSG Thread Forming Tap 1400138305 worldwide?

You can source the OSG Thread Forming Tap 1400138305 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 supply this tap to manufacturing facilities, maintenance shops, and engineering firms across multiple industries.

How to select the correct OSG Thread Forming Tap for your application?

To select the correct OSG Thread Forming Tap, match the thread size (e.g., 3/8"-24 UNF) and tolerance class (H5 for 2B-3B fit) to your workpiece material and thread requirements. Use a plug chamfer for through holes or blind holes with sufficient depth. TiN coating improves wear resistance in abrasive materials. Consult OSG's technical data for material-specific recommendations.
