Value Collection 84798859 M8 Split Lock Washer Grade 8

Product Description

The VALUE COLLECTION 84798859 is a metric split lock washer designed for use with M8 fasteners in bolted assemblies requiring vibration resistance and secure clamping force. Made from Grade 8 spring steel with a zinc plated finish, this washer provides consistent tension and bite to help prevent bolt loosening under dynamic or cyclic loads. The inside diameter ranges from 8.1 to 8.5mm, the outside diameter measures 14.8mm, and the thickness is 2mm. Hardness is rated at 44 to 51 HRC. This part conforms to DIN 127 and meets ASME, ANSI, BS, JIS, and NFE standards. It is a standard hardware component installed by maintenance technicians, millwrights, HVAC mechanics, and general contractors across a wide range of assemblies.

This split lock washer is suited for metric fastener applications in industrial, commercial, and residential settings. It is commonly used in equipment mounting, pipe support brackets, electrical panel assemblies, ductwork hangers, and structural connections where M8 bolts are specified. The zinc plated finish provides basic corrosion resistance for indoor and moderate-exposure applications. This part does not meet military specifications. Sold individually per package with a minimum order quantity of 100 pieces.

Compatibility

Designed for use with M8 metric screws and bolts in standard bolted assemblies. Compatible with any application requiring a DIN 127 metric split lock washer with an 8.1mm minimum inside diameter.

Installation Notes

Installation is performed by hand or with standard fastener tooling. Place the washer on the fastener shank against the workpiece surface before threading the nut or into a tapped hole. Ensure mating surfaces are clean and free of debris to allow proper washer seating and bite. De-energize and de-pressurize any system before accessing fastened assemblies in live mechanical, electrical, or piping installations.
