WASHER: TAB (P/N rsp71-1) - New Surplus

The rsp71-1 is a steel tab washer designed to prevent fastener loosening under vibration. This locking washer sits beneath a hex nut or bolt head, with one tab bent against a flat surface to mechanically lock the fastener in place. Commonly used in aircraft structural joints, control systems, and engine installations where vibration could otherwise cause fasteners to back out.

Installation follows FAA AC 43.13-1B guidance and NAS513-series specifications. The tab washer provides positive locking without requiring thread-locking compounds, making it ideal for maintenance and field repairs.
