OSG Thread Forming Tap: 5/8"-18 UNF, H4 / 2B-3B, Modified Bottoming Chamfer

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.

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.
