The VALUE COLLECTION MP31328 is a split lock washer designed to resist fastener loosening under vibration, dynamic loads, and thermal cycling. The split ring design bites into the mating surface and fastener bearing face when torqued, creating resistance against rotational loosening. This type of hardware is found throughout mechanical, HVAC, plumbing, and electrical assemblies wherever a standard bolt or screw joint requires added retention. Electricians, HVAC technicians, plumbers, and general tradespeople use split lock washers as a standard fastening component during equipment installation, panel work, and bracket mounting.
Split lock washers are used across residential and commercial applications in a wide range of assemblies, including equipment mounting, conduit support brackets, ductwork hardware, and structural fastening points. They are installed between the fastener bearing surface and the mating material to prevent loosening caused by vibration or movement over time. This washer is sold individually.
Designed as a general-purpose split lock washer suitable for standard fastening assemblies across mechanical and trade applications where vibration resistance is required.
Split lock washers are installed by any trade as part of a standard bolted joint. Place the washer between the fastener head or nut and the mating surface before torquing. Ensure the joint surfaces are clean and free of debris prior to assembly. Follow applicable mechanical and structural codes for fastener torque requirements based on bolt size and material.
