Écrou de fixation de l'hélice De Dietrich 300023646

A propeller fixing nut is a small but essential fastener used to secure the propeller or fan blade to the motor shaft in heating equipment. Without this nut, the propeller may become loose, leading to inefficient operation or damage. This component is commonly needed during boiler maintenance and repair when replacing fan motors or propellers. Made to fit standard propeller shafts, it ensures a tight and secure connection. As a simple yet critical part of burner spare parts, it helps maintain the reliability of your system.
