Value Collection 361010PR M3 Split Lock Washer Spring Steel

Product Description

The VALUE COLLECTION 361010PR is a metric split lock washer designed for use with M3 fasteners in bolted assemblies requiring vibration resistance. Made from Grade 8 spring steel with a zinc plated finish, this washer exerts spring tension when compressed under a fastener head or nut, resisting loosening caused by vibration and dynamic loads. The inside diameter ranges from 3.1 to 3.4mm, the outside diameter is 6.2mm, and the washer measures 0.8mm thick. Hardness runs 44 to 51 HRC. It conforms to DIN 127 and uses the metric system of measurement. Licensed tradespeople and assembly technicians install these in mechanical, electrical, and structural applications where M3 fasteners are specified.

This split lock washer is suited for light-duty metric fastener assemblies in residential and commercial applications. Typical uses include panel assemblies, electrical enclosures, equipment frames, and other installations where M3 machine screws or bolts require positive locking without thread-locking compound. The zinc plated finish provides basic corrosion resistance for indoor and protected environments. This part is sold individually but requires a minimum order quantity of 100 units.

Key Features

• Grade 8 spring steel construction with 44 to 51 HRC hardness for reliable spring action
• Zinc plated finish for basic corrosion protection in indoor or sheltered environments
• Conforms to DIN 127 fastener standard for metric split lock washers
• Inside diameter 3.1 to 3.4mm accommodates standard M3 fastener shank clearance
• 0.8mm thickness provides consistent clamp load distribution under fastener head or nut

Compatibility

Designed as an OEM-style replacement or standard hardware component for use with M3 metric fasteners in assemblies conforming to DIN 127 specifications.

Installation Notes

Install between the fastener head or nut and the mating surface with the split ends oriented to bite into both surfaces as the fastener is tightened. Ensure the fastener and mating material are clean and free of burrs before assembly. Always torque fasteners to the specification required by the assembly drawing or applicable standard. Do not reuse split lock washers that have been fully compressed flat, as they will not provide adequate spring action after yielding.
