Middleby 21422-0016 Split Lock Washer 1/2 Inch

Product Description

The MIDDLEBY 21422-0016 is a split lock washer used to secure fasteners in commercial foodservice and appliance assemblies. Split lock washers apply spring tension under a nut or bolt head, resisting loosening caused by vibration and thermal cycling. This washer is sized for 1/2-inch fasteners and is constructed from 18-8 stainless steel, providing corrosion resistance in wet or high-temperature service environments. It is a direct OEM replacement part intended for use during field service or in-shop repair of Middleby commercial equipment.

This split lock washer is suited for commercial kitchen equipment applications where fastener retention is critical. Typical install scenarios include reassembly of panels, burner components, motor mounts, and structural hardware on Middleby commercial appliances. The 18-8 stainless steel construction makes it appropriate for environments exposed to moisture, steam, or cleaning chemicals common in commercial foodservice settings.
