The Sierra International 18-3782 Marine Propeller Nut is a crucial component for securing your boat's propeller to the shaft. This nut is specifically designed to meet the demands of marine environments, ensuring reliable and durable performance.
This marine propeller nut is manufactured from high-quality, marine-grade brass. Brass is an excellent choice for this application due to its superior resistance to corrosion and seawater damage. The nut's brass construction also enhances its durability, making it able to withstand the rigors of frequent use in marine conditions.

This marine propeller nut comes with a locking collar included. The locking collar helps to prevent the nut from backing off, providing additional security and allowing for hassle-free operation. Installation and removal of the nut are facilitated by the six-sided flats on the nut's body that provide a superior grip when using a wrench.
Measuring 4.37 inches in length and 1.83 inches in width, this marine propeller nut is an essential addition to any boat's repair or maintenance kit. Its compact size makes it easy to store, transport, and carry.
