The basic thread lengths (LT) listed directly below the nominal sizes in the table above represents the nominal length up to which all screws of that diameter shall be fully threaded. To determine the threaded portion of the screws with a nominal length greater than LT, subtract the minimum design grip length (LG) from the nominal length (L).

5/8"-11 Hex Head Bolts have a 15/16"" hex head. The fastener length is measured under the head. The thread length is typically 1-3/4", but may vary.18-8 

These grade 8 yellow zinc plated fasteners are 5/8-11 thread and are 11" in length with a 2-1/4" thread and 15/16" hex.
