Value Collection R83920123 Split Lock Washer 8 Ss

Product Description

The VALUE COLLECTION R83920123 is a No. 8 split lock washer manufactured from 18-8 stainless steel. Split lock washers are used to resist fastener loosening caused by vibration and torque relaxation. The helical split design bites into the mating surface and the underside of the fastener head, maintaining clamp load after installation. The 18-8 stainless steel construction provides solid corrosion resistance in wet, coastal, and chemically active environments. Inside diameter ranges from 0.167 to 0.174 inches, outside diameter from 0.293 to 0.307 inches, and thickness is 0.04 inches. These washers are sold individually with a minimum order quantity of 500 pieces, making them appropriate for production and maintenance inventory stocking.

This split lock washer is suited for use in light industrial, commercial, and residential mechanical assemblies wherever a No. 8 machine screw or thread-forming screw is used. Common applications include panel fabrication, equipment mounting, electrical enclosure assembly, HVAC unit assembly, plumbing fixture mounting, and general mechanical fastening. The 18-8 stainless steel grade performs well in outdoor and high-humidity installations where zinc-plated hardware would corrode prematurely. Trades including electricians, HVAC technicians, plumbers, and mechanical contractors routinely use this washer size in both new construction and service applications.

Installation Notes

Install this washer between the fastener head and the mating surface with the split gap oriented consistently across the assembly. Ensure the mating surface is clean and free of debris before seating the washer to allow the split ends to engage properly. Do not reuse split lock washers that have been fully compressed flat, as the locking function is diminished. Torque fasteners per the assembly specification for the screw size and base material involved.
