Value Collection LWIS0621USA-100BX Split Lock Washer 100pk

Product Description

The VALUE COLLECTION LWIS0621USA-100BX is a Grade 2 spring steel split lock washer designed for use with 5/8 inch fasteners. The split lock design provides a spring action that resists loosening caused by vibration and torque relaxation. The washer carries a yellow zinc dichromate finish that provides corrosion resistance in moderately demanding environments. Inside diameter runs 0.628 to 0.641 inches, maximum outside diameter is 1.073 inches, and thickness is 0.156 inches. This box contains 100 washers, making it suitable for production runs, job-site stocking, and maintenance operations.

Split lock washers of this type are used across a wide range of mechanical and structural applications including HVAC equipment mounting, electrical panel assembly, plumbing fixture fastening, and general equipment fabrication. They are installed wherever a standard hex bolt or cap screw requires added resistance to vibration-induced loosening. The Grade 2 spring steel construction meets standard inch-system fastener requirements and is compatible with 5/8 inch bolts and screws in both light commercial and residential applications.

Compatibility

Designed as a standard inch-system replacement split lock washer for use with 5/8 inch screws and bolts in general mechanical, structural, and equipment assembly applications.

Installation Notes

Split lock washers are installed between the fastener head or nut and the mating surface before torquing the fastener to final specification. Ensure the split ends seat fully against both mating surfaces during assembly. Do not reuse compressed or fully flattened lock washers as they will not provide effective locking action. Installation should follow applicable mechanical or structural codes for the specific application.
