Frequently Asked Questions
What is an OSG thread forming tap used for?
An OSG thread forming tap creates internal threads by displacing material rather than cutting it, producing stronger threads in ductile materials like aluminum, brass, and low-carbon steel. This 5/8"-18 UNF cobalt tap with modified bottoming chamfer is ideal for blind-hole applications in automotive, aerospace, and general manufacturing.
What are the specifications of the OSG 5/8"-18 UNF thread forming tap?
This OSG tap has a 5/8"-18 UNF thread size, H4 / 2B-3B tolerance class, modified bottoming chamfer, and is made from cobalt for heat resistance. The manufacturer part number is 1400151700. It is designed for general-purpose thread forming in materials that allow plastic deformation.
