Frequently Asked Questions

What is OSG thread forming tap 1/4-28 UNF used for?

This OSG thread forming tap creates 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 OSG thread forming tap 1/4-28 UNF?

This OSG tap has a 1/4-28 UNF thread size, H7 / 2B tolerance, plug chamfer, and TiCN coated cobalt construction. The manufacturer part number is 1400129608. It is designed for general purpose thread forming in materials up to 850 °C hardness.

Where to buy OSG thread forming tap 1/4-28 UNF worldwide?

3G Electric supplies and delivers this OSG thread forming tap worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact us for availability and lead time on this MPN 1400129608.

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

Select based on thread size, tolerance class, chamfer type, and coating. For ductile materials, use a plug chamfer tap like this OSG 1/4-28 UNF with TiCN coating. Match the tap to your hole type (blind or through) and material hardness. Consult OSG's technical data for optimal speeds and feeds.
