"GRIP" For bolted connection.
"GRIP" For bolted connection.
(OP)
I was asked if I knew anything about "Grip" of a bolted connection to a C-Channel.
I have always known the term to indicate the thickness of engaged material related to length along the bolt.
My boss has a really old book which shows the "Grip" to be the correct location to put a hole in the flange of a beam.
Everything I Google relating to grip, results in bolt grip.
Is my boss's book correct and/or obsolete?
Is there another term used to indicate the proper location of a hole through a flange?
Thanks

Grip is defined in ASME B18.12 Glossary of Terms for Mechanical Fasteners

Thank you both.
I will try to get my hands on the book to post the title, but i just got two more projects dumped on my desk so I am a little swamped, so it might take me a day.

I have heard the term "grip" used to describe the unthreaded length of an AN (aircraft) bolt. I was also told that the bolt had to be long enough that the threaded portion was entirely outside the hole.

RE: "GRIP" For bolted connection.
yes, I agree with you.
I think I figured it out. The book does not show it clearly, at the bottem of the page is a note about finding the Gage location.
Basically it implies that Grip is the average flange thickness at the Gage location.

Yup: There's still a bit of confusion surrounding this one. The above definition is actually "effective length". That is, effective length of a stud in a through-hole. The effective length of bolts and studs fitted into blind holes is different still.
