Ensure your boat trailer’s roller assemblies spin smoothly and securely with the Seachoice 1/2" O.D. Roller Shaft. Engineered specifically to accommodate standard 3-inch keel, spool, or bow rollers, this heavy-duty axle shaft provides a dependable, high-strength axis that makes launching and loading your watercraft effortless.

As a trusted name in marine hardware, Seachoice packs this shaft with two matching 1/2" Pal Nuts (stamped locking nuts). This guarantees your roller stays locked in position, completely eliminating the risk of hardware backing off during highway transit or rough boat ramp launches.
