Value Collection 361220PR M22 Split Lock Washer Grade 8

Product Description

The VALUE COLLECTION 361220PR is an M22 metric split lock washer designed to resist fastener loosening under vibration and dynamic loads. Manufactured from Grade 8 spring steel with a zinc plated finish, it delivers reliable tension retention in bolted assemblies. The washer measures 22.5 inches to 23.5 inches minimum to maximum inside diameter, 35.9 inches maximum outside diameter, and 4 inches thick, conforming to DIN 127 standards. Hardness is rated at 44 to 51 HRC. Licensed tradespeople and mechanical assemblers install these washers in structural, industrial, and mechanical applications where fastener security is critical.

This washer is sized for M22 fasteners and is used in metric bolted connections across industrial machinery, structural steel assemblies, and heavy equipment maintenance. The zinc plated finish provides a baseline level of corrosion resistance suitable for indoor and light-exposure environments. It is sold individually per package with a minimum order quantity of 50 units, making it appropriate for shop stock, maintenance kits, or production line use.

Installation Notes

Split lock washers are installed between the fastener head or nut and the mating surface before torquing. Ensure the fastener, washer, and mating material are compatible in grade and finish before assembly. Do not reuse split lock washers that have been fully compressed or deformed, as they will not provide adequate locking force. Installation should follow applicable mechanical assembly standards and fastener manufacturer torque guidelines.
