Value Collection 36729 Split Lock Washer 1/2 in Alloy Steel 200pk

Product Description

The VALUE COLLECTION 36729 is a split lock washer sized for 1/2 inch screws, manufactured from AISI 4037 alloy steel with a zinc yellow dichromate finish. Split lock washers are used to resist loosening of threaded fasteners caused by vibration and torque relaxation. The 36729 features a 0.502 to 0.512 inch inside diameter, a maximum outside diameter of 0.869 inches, and a thickness of 0.125 inches. The zinc yellow dichromate coating provides corrosion resistance suitable for general industrial and mechanical applications. This package contains 200 washers. Installation is performed by licensed tradespeople and experienced technicians working with bolted assemblies.

Split lock washers in the 1/2 inch screw size are commonly used in HVAC equipment mounting, electrical panel and conduit hardware, plumbing fixture connections, and general mechanical assembly where fastener retention under vibration is required. The AISI 4037 alloy steel construction makes these washers appropriate for moderate-strength applications in both indoor and outdoor settings where a protective coating is present. These are sold in a package of 200, suiting both single-use service calls and shop-stock replenishment.

Installation Notes

Split lock washers are installed between the fastener head or nut and the mating surface before torquing. Ensure the fastener and mating threads are clean and free of debris before assembly. Do not reuse split lock washers that have been fully compressed flat, as they will no longer provide effective locking action. Follow applicable code requirements such as NEC or IFGC when using hardware in electrical or gas system assemblies.
