Rod End - 1/4in x 1/4in RH Steel - Male

The QA1 Rod End – 1/4in x 1/4in RH Steel – Male (CMR4) is a spherical rod end connector engineered for precision linkage applications where smooth articulation and load transfer are critical. Built from steel with zinc oxide corrosion protection, this male-threaded component is designed for high-cycle mechanical systems where alignment tolerances demand a true ball joint connection rather than a rigid fastener.

The 1/4-inch bore accepts a corresponding shaft pin, while the 1/4-28 right-hand threaded stud provides secure installation into a female-threaded receptacle. Steel construction delivers the strength required for sustained mechanical load, and the zinc oxide finish offers baseline corrosion resistance suitable for freshwater and protected marine environments. The compact footprint—measuring 3 x 0.4 x 5.6 inches and weighing just 0.04 lbs—makes it ideal for space-constrained linkage designs where weight matters.

This rod end is relied upon in boat steering systems, outboard trim-and-tilt mechanisms, and deck hardware linkages where the rod must pivot freely while transmitting force along its axis. Marine equipment engineers specify QA1 spherical rod ends when standard rod ends fail to accommodate the complex multi-plane motion found in modern marine control systems. The right-hand threaded configuration ensures compatibility with standard metric and imperial tapped holes found in marine aluminum and stainless steel frames.

For applications requiring dependable articulation in corrosive salt-air environments, consider upgrading to QA1's stainless steel variants or specifying additional protective coatings. This steel version delivers reliable performance in sheltered water systems and as a cost-effective OEM replacement where zinc protection is sufficient. Cross-reference your equipment's original part specifications to confirm bore size and thread pitch before ordering.
