Frequently Asked Questions

What is an OSG thread forming tap used for?

An OSG thread forming tap creates internal threads by displacing material rather than cutting it, producing stronger threads with no chips. It is ideal for ductile materials like aluminum, brass, and low-carbon steel in automotive, aerospace, and general manufacturing applications.

What are the specifications of the OSG 2866405 thread forming tap?

The OSG 2866405 is a 5/16"-24 UNF thread forming tap with a 2B class of fit, bottoming chamfer, and TiN coated high speed steel. It is designed for through or blind holes and provides excellent wear resistance and lubricity.

Where to buy OSG thread forming taps worldwide?

3G Electric supplies OSG thread forming taps like the 2866405 to customers worldwide. We handle full logistics, customs clearance, and delivery to your site, ensuring you get the right tool for your threading needs without inventory constraints.

How to select the right OSG thread forming tap for my application?

Select an OSG thread forming tap based on thread size (e.g., 5/16"-24 UNF), material type, and hole condition. For blind holes, use a bottoming chamfer like this TiN coated tap. Ensure the tap matches the required class of fit (2B) and coating for your workpiece hardness.
