Optimist Mast Step Nut
Optiparts # EX1207
The Optiparts Optimist Sailboat Mast Step Nut is designed for use with the Optiparts adjustable mast step. The integrated brass insert reduces friction during adjustment, allowing smooth and precise mast rake changes while minimizing wear on the threaded spindle.
The nut can also be used as a backing nut to minimize play within the mast step assembly.
