The 9975 Series Bareco split (cotter) pins are zinc plated split pins used to secure castellated nuts, retain pins through holes, and lock components in place against working loads. Where R-clips need a groove machined into the pin to retain, cotter pins simply pass through a hole in the pin and bend over — they fit any drilled-through pin without modification.

Used on tractor steering tie rod ends, three-point linkage pins, agricultural machinery shafts, trailer hitches and any application where a castellated nut needs locking. Each pack contains 50 pins for service workshop or trade use.
