Value Collection 86853231 3/8 Inch Grade 8 Split Lock Washer 50 Pack

Product Description

The VALUE COLLECTION 86853231 is a Grade 8 alloy steel split lock washer designed for 3/8 inch fasteners. The zinc plated finish provides corrosion resistance in demanding environments. Each washer measures 0.377 to 0.385 inches inside diameter and 0.586 to 0.680 inches outside diameter, with a thickness of 0.094 to 0.140 inches. The split lock design applies spring tension under the fastener head to resist loosening from vibration and dynamic loads. This package contains 50 washers, making it a practical bench stock item for mechanical, HVAC, plumbing, and electrical assembly work.

Grade 8 split lock washers are used wherever high-strength fastener assemblies require vibration resistance. Common applications include equipment mounting, structural bracketing, and mechanical assembly in residential and light commercial installations. The 3/8 inch screw size is widely used in HVAC unit mounting, electrical panel work, pipe support hangers, and general trade fabrication. These washers are suitable for use with Grade 8 bolts and fasteners in inch-measurement systems.

Compatibility

Designed for use with 3/8 inch Grade 8 bolts and fasteners in inch-measurement fastener assemblies across mechanical, HVAC, plumbing, and electrical trade applications.

Installation Notes

Installation is performed by mechanics, HVAC technicians, plumbers, and electricians as part of standard fastener assembly. Place the split lock washer between the fastener head or nut and the mating surface before torquing. Ensure the fastener, washer grade, and base material are compatible to avoid galvanic corrosion or joint failure. Always de-energize equipment and relieve system pressure before servicing any assembly that requires fastener removal.
