Frequently Asked Questions

What is OSG thread forming tap #4-40 UNC used for?

OSG thread forming taps create internal threads in ductile materials like aluminum, brass, and steel without cutting chips. The #4-40 UNC size with bottoming chamfer suits blind holes. TiN coating reduces friction and extends tool life in production machining.

What are the specifications of OSG thread forming tap 1400157305?

This OSG tap is #4-40 UNC thread size, H6 / 2B tolerance class, bottoming chamfer, TiN coated cobalt construction. Manufacturer part number 1400157305. It forms threads by displacing material, ideal for through or blind holes in ductile workpieces.

Where to buy OSG thread forming tap #4-40 UNC worldwide?

3G Electric supplies OSG thread forming taps worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this #4-40 UNC TiN coated tap. We source genuine OSG tooling for global industrial customers.

How to select the right OSG thread forming tap for aluminum?

For aluminum, choose a thread forming tap with TiN coating like this OSG #4-40 UNC model. Ensure hole size matches the recommended drill diameter for forming taps. Use proper lubrication to reduce friction and prevent galling. OSG taps are designed for consistent thread quality in ductile materials.
