Description
Jumbo flat washers are designed for large bolts up to 4? diameter. Washer is suitable for applications that require spacer, shim, or other reinforcement in industries including construction, power generation, machinery, and transportation. The washer is made from 4140 steel, a chromium-molybdenum steel alloy. The benefits of alloy steel include its tensile strength, yield strength, fatigue resistance, toughness, and wear resistance. The washer?s size corresponds to matching screw or bolt size. Inner diameter is manufactured 1/8" larger than the bolt to allow for slight alignment issues, and to accommodate a thicker bolt shank. Extra-large outer diameters and thicknesses up to 5/16" provide extra bearing surface and extra strength.Washers have a variety of purposes. They can distribute the load of a threaded fastener and can also be used as spacers, springs, shims, and locking devices. Washers can be measured in inches or in millimeters, and typically have an outer diameter about twice
