The old catalogue needed to be updated, it listed the wrong nut (I think it was Part#8050321 which seized on the anchor pins). The correct nut is Part#8050311 5/16-18 NYLOCK. This is the exact same nut that comes with the rudder stiffening kit. Peace.
The (8050311 5/16-18 NYLOCK) nut is not to spec for depth. The original nut, as described by me earlier in this thread, was a heavy duty nut with more thread depth. That is why we decided to just list the anchor bar now... the original nut was no longer available. The anchor bar works great.
The original was NUT 5/16-18 NYLOCK HVY
It did not seize... purposefully.
Hi Matt, In the past, before the bar was introduced for the 18, you steered us to part#8050311 (see link below. ). I took your advise and the part worked fine - no problems whasoever under fairly heavy use. The nut that seized on the pins, 8050321, did so because it was incorrectly labeled in the OLD catalogue. I know this because it cost me a headache and my dealer two shroud anchor pins. The old catalogue also lists the nut you recommended in the post linked below, 8050311, as the nut for your rudders I.e., the nut that comes (or at least used to come with) with the rudder stiffening kit. Where am I wrong?viewtopic.php?f=13&t=14013&p=94525&hilit=8050311#p94525
