I did try to search this.

Recently while rebedding my stanchions I noticed the nuts and bolts which hold the Deck and Hull together since I was using a 7/16 on the stanchions anyway I put my wrench on one and it wasn't very tight more than finger tight but not by a lot. So I emailed Catalina to see if there was a particular torque they should be at but I never heard back from them.  :cry4` does anyone know about these?

TIA

Why not use the good old phone, call FL, ask for Warren and he'll get an answer if there is one.

You really don't need anybody else to tell you anything.  Just tighten it up snug, short of the threshold of pain (for your joints!!!:D) and be done with it.  Really.  The ONLY torque I think is critical are the keel bolts.

Saves a long distance phone call.  Send Ken the $$ you woulda saved.   :D :thumb: :D

PS - added later  Jim, hope I didn't sound harsh.  You're right, I don't EVER recall hearing about this.  Fun to be first?!?  :shock: :clap

And since you now have that stanchion rebedding "thing" down how'bout swinging by San Diego and give mine a go, too. BTW-I also need backing plates added. 8)

Stu, not at all. I think I will call them though some things you can mess up by unequal tightening I'd hate to cause that seal to leak from not doing it right.

Yeah, no, but if you ever sail down to Ensenada I'm at Cruiseport I'll buy you a taco.   8)

So I talked to Warren at Catalina and he basically said what Stu said, get them tight like you'd tighten any other nut. Also he didn't really sound like it was an issue I should be too concerned with.

Jim : Somewhere in the Mainsheet Tech Notes I published the factory spec.!! 
As I'm recalling (in this 86year old mind), it was something like 107 foot pounds??
 
Like Stu said "tighten till the pain starts"!!

Are the hull to deck joint screws you're talking about the ones that are less than 1/2" diameter? Maybe 5/16-7/16"?

In the boat they are nuts on bolts.

What size? Torque value depends on grade, fine or coarse thread, size, and whether plain or plated. Example torque for grade 5, 7/16", not plated, is 50-55 ft lbs. If plated it's 37-41 ft lbs. (coarse vs fine thread)

I think the 107 foot pounds of torque is in reference to the keel bolts.
