Value Collection LWIS0251USA-100BX Split Lock Washer 100 Pack

Product Description

The VALUE COLLECTION LWIS0251USA-100BX is a Grade 2 spring steel split lock washer sized for 1/4 inch screws. The split lock design applies axial tension under the fastener head, resisting loosening caused by vibration and dynamic loads. With a 0.252 inch minimum inside diameter, 0.487 inch maximum outside diameter, and 0.062 inch thickness, this washer fits standard 1/4 inch fastener assemblies. A zinc yellow dichromate finish provides corrosion resistance in mild service environments. This box contains 100 washers, making it a practical stock quantity for field kits or shop inventory. Electricians, plumbers, HVAC technicians, and mechanical contractors commonly use split lock washers when securing panels, brackets, pipe hangers, and equipment mounts.

Split lock washers in this size class are used across a wide range of light- to medium-duty fastening applications in residential and commercial construction and maintenance. Typical installations include electrical panel and conduit bracket fastening, HVAC equipment mounting, plumbing hanger rod assemblies, and general mechanical hardware. The inch-system sizing and standard Grade 2 material specification make this washer compatible with common hardware encountered in everyday trade work. The zinc yellow dichromate finish suits indoor and sheltered outdoor environments where mild corrosion resistance is sufficient.

Installation Notes

Split lock washers are installed between the fastener head or nut and the mating surface before final torque is applied. Power down electrical equipment and isolate any pressurized systems before servicing fastened connections. Use appropriate hand tools or power drivers set to controlled torque to avoid flattening the split, which reduces locking effectiveness. Follow applicable NEC, IPC, or IFGC guidelines when installing hardware within regulated systems.
