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

Jul 22 2020 · 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.

Bolt Boot Camp 6 Things to Know About Threaded Fasteners

Apr 25 2020 · This is a very confusing principle for new engineers because some bolts are screws and others are not. For example a carriage bolt is often used as a screw and a socket head cap screw (SHCS) is often used as a bolt. The simple answer is a bolt uses a nut while a screw does not. Screws thread directly into one of the pieces of material to be
