Stewart Fastener J25WLZ 1/4 Inch Zinc Lock Washer 100 Pack

Product Description

The STEWART FASTENER J25WLZ is a 1/4 inch split lock washer with a zinc plating finish, sold in a jar of 100 pieces. Lock washers of this type are used to prevent fastener loosening caused by vibration, torque, and thermal cycling. The helical split design bites into both the fastener bearing surface and the mating material, maintaining clamp load over the service life of the assembly. These are a standard hardware item stocked and used by HVAC technicians, plumbers, electricians, and general mechanical contractors across residential and commercial applications.

Split lock washers in this size are commonly used with 1/4 inch machine screws and bolts in equipment mounting, panel fastening, pipe hanger assemblies, electrical enclosure work, and unit installations. The zinc plating provides basic corrosion resistance suitable for indoor and light-duty outdoor service. The jar packaging keeps fasteners organized and countable on the job site or in a service van parts inventory.
