Closed-Body Rigging Screw

The closed barrel keeps water and grit off the threads and gives a clean visual line at the chainplate. Rolled threads for fatigue life, with a lock nut at each end.

• Closed body keeps salt and grit out of the thread, the usual cause of seizure at refit.
• Rolled threads improve fatigue life at the root compared with cut threads.
• Lock nuts at both ends, plus a drilled fork pin for split ring or mousing wire.
• Barrel and studs sold separately as spares for long-term fleet support.
