Value Collection 36730 Split Lock Washer 9/16 in 100 Pack

Product Description

The VALUE COLLECTION 36730 is a split lock washer sized for 9/16 inch screws, manufactured from AISI 4037 alloy steel with a zinc yellow dichromate finish. Split lock washers are installed under fastener heads or nuts to resist loosening caused by vibration and torque relaxation. The helical split design bites into both the fastener bearing surface and the mating material when the fastener is tightened, providing mechanical resistance to rotation. This washer measures 0.564 to 0.574 inches inside diameter, 0.965 inches maximum outside diameter, and 0.141 inches thick. The zinc yellow dichromate coating provides corrosion resistance for general industrial and mechanical assembly applications. Sold in a package of 100 pieces.

This split lock washer is suited for use in general mechanical assemblies, HVAC equipment mounting, electrical panel and enclosure fastening, plumbing fixture installation, and light structural connections where vibration resistance is required. The 9/16 inch screw size makes it compatible with standard fractional fastener hardware commonly used in trade and industrial settings. Installers working on equipment that experiences operational vibration, such as compressors, fan assemblies, and pump mounts, will find this washer appropriate for maintaining fastener preload over time.

Installation Notes

Install split lock washers between the fastener head or nut and the mating surface before tightening. Ensure the fastener, washer, and mating material are clean and free of debris prior to assembly. Tighten fasteners to the torque specification required by the assembly design, not the washer itself. No special tools are required beyond standard hand or power fastening equipment.
