Grade 8 Hex Bolt Yellow Zinc Plated:
Grade 8 hex bolts are made from medium carbon alloy steel and heat treated. A Grade 8 hex bolt has a greater tensile strength than a Grade 5 and Grade 2 hex bolt. They are designed for use in high stress applications. 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 1 pound. Bolts over 6" could be plain steel or yellow zinc.
