WASHER (P/N sp41e) - New Surplus

The sp41e is a straight tab washer made of mild steel, designed for 1/4 inch BSF screws. This locking washer resists bolt and nut loosening under vibration by bending a tab against the mating surface after torque application. Commonly installed in Hawker 800/800XP, 850XP, and 900XP aircraft assemblies where vibration resistance is critical.

Installation follows AC 43.13-1B guidance: position the washer on the mating surface, apply torque per aircraft maintenance manual specifications, then bend the tab securely against the fastener.
