Grade 5 Hex Bolt - Zinc - Coarse Thread
(##) Number of Pieces in 1 Pound
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. Please note you are buying by the pound so confirm your pieces when considering how much to purchase. (##) Number of pieces in the 1 pound increment.
