Threads on parallel fasteners use a cylindrical blank having an outside diameter between the major and minor diameters of the finished thread. A bar is rotated between hardened steel dies bearing the reverse thread form. The die threads penetrate the blank surface to form the thread roots and displace material radially outward to form the crests.

Thread Basics:Go / No-Go Acceptance 2018-01-01

Jan 01, 2018 · The basic concept of a thread plug is to provide a quick inspection for machinists and quality inspectors to verify that the threads are within the accepted tolerance so that it interacts with the mating part correctly. This verification would be performed by threading the Go thread gage to the full depth of the feature without restriction, followed by the non-acceptance of the No-Go plug gage.
