Grade 8.8 metric cap screws, sometimes referred to as bolts, are medium strength with a tensile rating of 120,000 psi. They are usually silver in color with a zinc coating to help prohibit rust. Lengths up to 30mm are fully threaded and bolts longer than 30mm may be partially or fully threaded. Quantity discounts are listed near the bottom of the product page. These are similar to US Grade 5 steel.
