Frequently Asked Questions

What is the OSG Thread Forming Tap 1/4"-28 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 chips. It is ideal for automotive, aerospace, and general manufacturing applications requiring strong, burr-free threads in blind or through holes.

What are the specifications of the OSG Thread Forming Tap 1/4"-28 UNF?

This OSG tap has a 1/4"-28 UNF thread size, H9 tolerance, plug chamfer, and TiCN coating on cobalt steel. The manufacturer part number is 1400129808. It is designed for general purpose thread forming in materials up to 850 MPa tensile strength.

Where to buy the OSG Thread Forming Tap 1/4"-28 UNF worldwide?

You can source the OSG Thread Forming Tap 1/4"-28 UNF from 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.

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

Select based on thread size (e.g., 1/4"-28 UNF), material hardness, and tolerance class (H9 for standard fits). For ductile materials, use TiCN-coated taps for longer life. Ensure hole size matches the tap's recommended drill diameter to avoid breakage or poor thread quality.
