Frequently Asked Questions

What is OSG thread forming tap #5-40 UNC 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 #5-40 UNC?

This OSG tap is #5-40 UNC with H4 / 2B-3B tolerance, plug chamfer, and TiCN coated cobalt construction. The TiCN coating reduces friction and extends tool life in abrasive materials. It is designed for general purpose thread forming in production environments.

How to select the right thread forming tap for aluminum?

For aluminum, choose a thread forming tap with TiCN coating like this OSG #5-40 UNC model to reduce galling. Ensure the tap tolerance (H4 / 2B-3B) matches your required thread class. Use proper lubrication and a rigid tapping cycle to prevent breakage in soft materials.
