T bolt threads partially unscrewed? Can I sail??

[Sailor_Grant]

When tuning my rig I noticed the T Bolt Threads twisting as well, I made sure to tighten them back in the best I could by loosening shroud and using backing bolt again turnbuckle to screw them in.

It seems that tightening the turnbuckle to the left has the ability to loose toosten the t bolt.

I was able to fix the problem with vise grips and properly tune rig, however, it only screwed in this much (which is how much I think was in there before).

Does this look unscrewed too much from people with experience with these fittings?

Get rid of those asap. Water gets into the fitting and causes severe crevice corrosion. They haven't made those for quite a while meaning they're old and way overdue for replacement. I have pictures of them completely falling apart when unloosening to re-rig.

No. There is a small rollpin which holds the toggle nut in place which has clearly failed. You can purchase a replacement from C.S. Johnson.

Is there any benefit to the toggle nut design like CS Johnson carries?

Or can I use this design:

Hi. Please do not sail like this. Carefully proceed to a boatyard that can pull your mast ASAP. It’s not a big mast but it can hurt or kill someone.Find a good rigger.
You need to fix this correctly and now. It will be far less expensive than paying for an attorney if anyone gets hurt.
Sorry, but I don’t like to see anyone hurt.

You may be able to replace the bottom screw and saddle with a fork and a toggle without taking the mast down.
That fitting does look like the screw has backed out of the barrel nut.

I was able to replace all the T-Toggles and turnbuckles on all lower and upper shrouds. The new T Toggles are one solid piece, so it is impossible to unscrew.

This winter I am going to drop the mast and replace all standing rigging.

Good solution and a good plan of action. The rigging should definitely be checked.
