Value Collection 87925202 Split Lock Washer 1/2 in 18-8 Ss

Product Description

The VALUE COLLECTION 87925202 is an 18-8 stainless steel split lock washer sized for 1/2 inch screws and bolts. Also called a spring lock washer, it works by applying tension against the fastener as the joint is tightened, resisting loosening caused by vibration and thermal cycling. The inner diameter ranges from 0.502 to 0.512 inches, the maximum outer diameter is 0.869 inches, and the washer thickness is 0.125 inches. The 18-8 stainless steel construction provides corrosion resistance suitable for indoor and outdoor mechanical assemblies. Plumbers, HVAC technicians, electricians, and general maintenance trades use these washers in equipment installations and structural fastening applications.

This split lock washer is suited for use in residential and commercial mechanical, plumbing, electrical, and HVAC installations where vibration-resistant fastening is required. It is appropriate for use in equipment mounting, pipe support brackets, panel assemblies, and similar trade applications. The washer conforms to ASME, ANSI, BS, DIN, JIS, and NFE standards, making it broadly applicable across domestic and internationally specified projects. These are sold in a minimum order quantity of 100 pieces, consistent with trade and contractor purchasing requirements.

Installation Notes

Install the split lock washer between the fastener head or nut and the mating surface before torquing. Ensure the washer gap is properly seated and not pre-flattened before use, as a fully compressed washer no longer provides locking tension. Follow applicable torque specifications for the fastener grade and joint material. No special tools are required beyond standard hand or power torque equipment.
