Place a nonmetallic bearing surface between a fastener and its mating material with this nylon washer. Its 0.222 in inside diameter provides the fastener-clearance dimension, while its 0.5 in outside diameter defines the area supported around the hole. These dimensions are the primary fit checks when replacing a washer or assembling compatible hardware. JA 5610-114-40 provides nylon construction for applications that need a washer at a fastener interface rather than a metal contact surface. It can separate adjoining surfaces, spread fastening force over its outside diameter, and help protect the material directly under a fastener head or nut. Select the washer by measuring the required hole clearance and available bearing area. For mobile medical cart hardware, use it only where the assembly calls for a nylon washer with these stated diameters. The washer is a small mechanical component, not a cart, workstation, display, or electronic accessory. Do not substitute it where the assembly requires a different inside diameter, outside diameter, thickness, material, or a formed spacer. The stated dimensions allow direct comparison with an existing washer before removal. Verify the mating fastener and surrounding surface before installation.
