Value Collection HLWIA087USA-100BX Split Lock Washer

Product Description

The VALUE COLLECTION HLWIA087USA-100BX is a high collar split lock washer designed for use with 7/8 inch screws. Made from uncoated steel, this washer features a helical split design that creates tension under the fastener head to resist loosening caused by vibration and torque. The inside diameter ranges from 0.887 to 0.905 inches with a maximum outside diameter of 1.296 inches and a thickness of 0.234 inches. This item is sold in a minimum order quantity of 100 units. It is a standard inch-measurement fastener suitable for general mechanical assembly, structural connections, and equipment installation across trade applications.

High collar split lock washers are commonly used in HVAC equipment assembly, electrical panel and enclosure mounting, plumbing fixture installation, and general industrial fastening where vibration resistance is required. The high collar profile provides greater spring tension than standard split lock washers, making it well suited for applications where joint integrity under dynamic load is a priority. This washer is appropriate for residential and light commercial applications handled by licensed tradespeople and general contractors.

Compatibility

Designed for use with standard 7/8 inch SAE screws and bolts in inch-measurement fastener applications. Suitable as a general-purpose split lock washer in mechanical assembly, equipment mounting, and structural fastening where a high collar profile is specified.

Installation Notes

Install with the split gap oriented away from the fastener bearing surface before seating the bolt or screw head. Power down or de-energize any equipment before accessing fastener assemblies in electrical or HVAC applications. Use appropriate hand tools and torque wrenches to avoid over-compression, which can reduce the washer's locking effectiveness. Follow applicable codes and equipment manufacturer guidelines for fastener torque requirements.
