Grade 5 bolts are the most common type we carry and have a minimum tensile strength of 120,000 psi. They are silver in color with a zinc coating to help prohibit rust. Sizes up to 1-1/4" are fully threaded and most sizes longer than 1-1/4" are partially threaded(with between 3/4" and 1-1/4" of thread at the end). Quantity discounts are listed near the bottom of the product page.
