5/16"-18 Grade 5 Hex Tap Bolt

Grade 5 Hex Tap Bolt:  The hex head bolt has the six sided hexagonal shaped head. This is a machine threaded bolt typically used with a nut or in a pre-threaded hole.  The Grade 5 bolt can be distinguished by the 3 dashes (l) on top of the head of the bolt, please see photo below.  Grade 5 hex bolts shall be heat treated, at the option of the manufacturer and tempered to a minimum tempering temperature of 800 degrees Fahrenheit.  A Grade 5 hex bolt has greater tensile strength than a Grade 2 hex bolt, and its yield to tensile ratio is the lowest of all heat treated steels.  The length of a hex bolt is determined by measuring from under the head of the bolt to the base of the threads. A "tap" bolt is fully threaded.  Please note you are buying by the pound so confirm your pieces when considering how much to purchase. (##) Number of pieces in 1 pound
