What is the shank length or grip length of a bolt?
A- There are two terms that describe the smooth area between the head and threads on a bolt, “SHANK” and “GRIP”. Both terms are correct to describe the smooth area on a bolt. All shear loads should be positioned on the Shank/Grip area of a bolt. Shank/Grip length is measured from the start of smooth area under the head and ends where the threads start.
