1、Grade 8 Alloy Steel Bolts Common uses for grade 8 bolts are for military, aerospace, or marine related mechanical applications where high stress and strong load bearing pressures are a major factor.
2、Grade 8 bolts are medium carbon alloy steel, quenched and tempered at a minimum temperature of 800 degrees Fahrenheit. They are then heat-treated to achieve a hardness of 33 to 39 on the Rockwell C scale.
3、Grade 8 Alloy Steel Bolts Made from Grade 8 steel, these screws can be used in high-stress applications, such as valves, pumps, motors, and automotive suspension systems. They are more than twice as strong as our stainless steel thread-locking screws. A nylon patch bonded to the threads adds friction to resist loosening from vibration. These screws have a zinc yellow-chromate plating that provides corrosion resistance in wet environments.
