Value Collection MP42455 M10 Split Lock Washer Grade 8 50pk

Product Description

The VALUE COLLECTION MP42455 is a metric split lock washer designed for use with M10 fasteners in bolted assemblies requiring positive locking action. Manufactured from Grade 8 spring steel with a zinc-plated finish, this washer resists loosening caused by vibration and dynamic loads. The split design creates a spring-like bite against the mating surfaces when the fastener is torqued down, maintaining clamp load over time. Inside diameter runs 10.2 to 10.7mm with a maximum outside diameter of 18.1mm and a thickness of 2.2mm. Hardness is rated Rockwell C44 to C51. Conforms to DIN 127 fastener standard. Sold in a package of 50.

Split lock washers of this type are used across a wide range of trade and industrial applications including mechanical equipment assembly, structural fastening, HVAC unit mounting, electrical enclosure hardware, and general maintenance work. The M10 size is common in metric-hardware installations found in commercial and residential mechanical systems. Zinc plating provides basic corrosion resistance suitable for indoor and sheltered outdoor environments. These washers are installed by HVAC technicians, electricians, plumbers, and general maintenance mechanics wherever M10 fasteners require vibration resistance.

Installation Notes

Install between the fastener head or nut and the mating surface with the split gap oriented away from the bearing surface where practical. Ensure the fastener and washer are clean and free of debris before assembly. No special tools are required beyond standard hand or power torque equipment appropriate for M10 hardware. Follow applicable equipment manufacturer torque guidelines for the specific joint being assembled.
