Value Collection LWIS037GUSA-100BX 3/8 in Steel Split Lock Washer

Product Description

The VALUE COLLECTION LWIS037GUSA-100BX is a 3/8 inch steel split lock washer with a hot-dipped galvanized finish, sold in a minimum quantity of 100 pieces. Split lock washers are installed under fastener heads or nuts to resist loosening caused by vibration, torque relaxation, and thermal cycling. The washer features an inside diameter of 0.382 to 0.385 inches and an outside diameter of 0.680 to 0.683 inches, with a thickness of 0.094 inches. The hot-dipped galvanized coating provides corrosion resistance in exposed or damp environments. Electricians, plumbers, HVAC technicians, and general contractors use these washers in panel installations, pipe hangers, equipment mounting, and structural fastening applications.

This split lock washer is suited for residential and commercial trade applications where a standard 3/8 inch fastener is used and vibration resistance is required. Typical uses include equipment mounting brackets, electrical enclosure assemblies, HVAC unit fastening, and plumbing hanger rod connections. The galvanized finish makes it appropriate for installations where moisture exposure is a concern, such as mechanical rooms, rooftop units, and outdoor structural connections. The package quantity of 100 pieces supports volume fastening tasks on job sites.

Installation Notes

Install with the split gap positioned so that both cut edges bear against the fastener and mating surface as the fastener is tightened. Power down or de-energize any electrical equipment before installing hardware in or around live panels. Use appropriate hand tools and follow torque guidelines specified in the equipment manufacturer documentation or applicable codes such as NEC for electrical assemblies. Inspect washers for deformation before installation and discard any that show cracks or incomplete galvanizing.
