Frequently Asked Questions

What is the OSG Thread Forming Tap 1/4"-20 UNC used for?

This OSG thread forming tap is used to create internal threads in metal without cutting, ideal for ductile materials like aluminum and steel. It is commonly applied in automotive, aerospace, and general manufacturing for producing strong, burr-free threads in through or blind holes.

What are the specifications of the OSG Thread Forming Tap 1/4"-20 UNC?

This OSG tap has a 1/4"-20 UNC thread size, H5 / 2B-3B tolerance, bottoming chamfer, and black oxide cobalt finish. The manufacturer part number is 1400125601. It is designed for general purpose thread forming in ductile materials.

Where to buy the OSG Thread Forming Tap 1/4"-20 UNC worldwide?

You can source the OSG Thread Forming Tap 1/4"-20 UNC worldwide through 3G Electric. We handle full logistics, customs clearance, and delivery to global destinations. Contact us for availability and lead time; we supply this tap as part of our extensive industrial equipment range.

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

Select an OSG thread forming tap based on material type, thread size, and hole condition. For ductile materials like aluminum or low-carbon steel, use a forming tap with bottoming chamfer for blind holes. Ensure the tap tolerance (e.g., H5) matches the required thread class (2B-3B). Consult OSG's technical data for optimal performance.
