Value Collection 361180PR M18 Split Lock Washer Grade 8

Product Description

The VALUE COLLECTION 361180PR is a metric split lock washer designed for use with M18 fasteners in bolted assemblies requiring reliable tension retention. 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.

This 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.

Compatibility

Designed for use with M18 metric fasteners in assemblies conforming to DIN 127 specifications. No specific equipment model compatibility was provided by the manufacturer for this part number.

Installation Notes

This washer is installed by mechanics, pipefitters, and millwrights as part of standard bolted joint assembly. Place the split lock washer between the nut or bolt head and the mating surface before torquing. Ensure mating surfaces are clean and free of debris to allow full seating of the washer. Always follow applicable mechanical codes and equipment manufacturer torque guidelines when completing the assembly.
