ASME B18.21.1 Spring Washer are widely used in load-bearing and non-load-bearing structures of general mechanical products. They are characterized by low cost and convenient installation, and are suitable for the parts with frequent assembly and disassembly. ASME B18.21.1 Spring Washer in the screw industry, often called ASME B18.21.1 Spring Washer. The benefit of spring lock washers lies in the trapezoidal shape of the washer. When compressed to loads near the proof strength of the bolt, it will twist and flatten. This reduces the spring rate of the bolted joint which allows it to maintain more force under the same vibration levels. This prevents loosening.

ASTM F436m Hardened HDG Flat Washer is stamped piece from, The shape is round with a hole in the middle. ASTM F436m Hardened HDG Flat Washer have a smooth bearing surface which is used under the head of a bolt, ASTM F436m Hardened HDG Flat Washer are used to reduce friction, The force is unoform, It is not easy to slip and lock in the process of rotation, and it is anti loose design, prevent leakage, isolate, prevent loosening, or distribute pressure.

DIN6915 10 Hv Heavy Hex Nuts also called structural nuts, are both thicker and wider than a standard (finished) hex nut and compatible with high strength and large diameter bolts. DIN6915 10 Hv Heavy Hex Nuts in sizes smaller than 7/16" are double chamfered. DIN6915 10 Hv Heavy Hex Nuts larger than 7/16" are either double chamfered or chamfered on top with a washer faced bearing surface.
