Almost lost a trim tab. The Delrin pin broke holding the actuator to the tab. The screws holding the hinge came out and was hanging by one screw. The 2007 Lenco manual says to use a stainless hex nut they must have had issues with the Delrin pin. Has anyone replaced the pin with the stainless hex screw? Also I noticed that the hinges were mounted with oval head screws not stainless sheet metal screws I'll be changing those too.
