Typically, structural bolt (ASTM A325/A490) lengths are calculated as the grip (plate, material bolting) plus the thickness of the washer and nut. However, this formula may change depending on your specific application. Feel free to contact us about with more information.

(exp 3/4" diameter bolt) I know the plate thickness and the steel member thickness have to take into consideration. What else? Can anyone explain to me and show me the example to determine the final bolt length? Thanks Can I know how to determine the bolt length for specific bolt size based on the shop drawings?
