Manufactured from Grade 8 spring steel with a zinc plated finish, this washer resists loosening caused by vibration and dynamic loading. It measures 18.2 inches minimum inside diameter, 29.4 mm maximum outside diameter, and 3.5 mm thick, conforming to DIN 127 standards. Hardness ranges from 44 to 51 HRC, providing the elastic bite needed to maintain clamp load. Plumbers, pipefitters, millwrights, and mechanical contractors install this type of hardware in structural and equipment-mounting applications.\u003c\/p\u003e\n\u003cp\u003eThis split lock washer suits metric bolted connections in industrial, commercial, and mechanical equipment installations. It is appropriate wherever an M18 fastener is torqued into a joint that will experience vibration, thermal cycling, or repeated loading. The DIN 127 fastener standard makes it compatible with metric assemblies across HVAC equipment frames, pump bases, pipe supports, and general structural fabrication. Minimum order quantity is 100 pieces per order, with individual package quantity of one.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade 8 spring steel construction with 44 to 51 HRC hardness for consistent elastic clamping force\u003c\/li\u003e\n  \u003cli\u003eZinc plated finish provides basic corrosion resistance for indoor and light-duty applications\u003c\/li\u003e\n  \u003cli\u003eConforms to DIN 127 metric fastener standard\u003c\/li\u003e\n  \u003cli\u003eInside diameter range of 18.2 to 19.0 mm fits M18 fastener shank tolerances\u003c\/li\u003e\n  \u003cli\u003e3.5 mm thickness delivers adequate bite depth for vibration resistance in bolted joints\u003c\/li\u003e\n  \u003cli\u003eMinimum order quantity of 100 units suits bulk service and shop stock applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with M18 metric fasteners in assemblies conforming to DIN 127 specifications.
