Pulled this thread up from a search on what bolts.

Sadly most of the links don't work anymore.
My engine bolts go through the bracket, transom and then through a peice of steel box section (1 going across the top two bolts and one across the bottom 2).
I want to do away with the 2 pieces of box section and instead fit thick Stain less steel plates to spread the load on each nut. But this will leave me with 4 very long bolts sticking out of the transom waiting to make someone bleed.
(get on with it!!)

So where do I buy 4 nuts and bolts from that (?) isn't going to course a " Your not spending more money on that boat!!" argument with the witch in doors.

Can I assume the bolts stick into the boat ( hence possibly draw blood) ? If this is the case can you just turn them round so they stick 'out' of the boat ?

Ah but they're so long I wouldn't like them sticking out the back either. They are going from going through, say, a 2 inch box section to going through a 5mm S/S plate.
Not sure if this is right but have always been told to replace a torqued up bolt and nut for a shiny one?

I will admit I would be very very tempted to take a hacksaw to them ( carefully)- leave the nuts on to clean up the thread & hey presto shorter bolts ! I cant think they would fail if they are any good and are 'probably' well within any margin of safety before they fail.

It's an idea mate! Wonder if I could get a plate with a cut out so I can just slide them over the bolt and tighten the but up. That way I don't even have to unscrew the fecker

These are pretty cheap!!!

There is nothing wrong with cutting off the bolts and running a die down them afterwards if you know what you are doing.

I'm tempted by the idea of cutting the box section out from around the back of the nut. Then cut a section out of the S/S washer to the centre hole. (LINK)
Then over lap two washers, one sliding over the top of the bolt and one sliding up from the bottom and torque the nut up onto these. Then cut the excess bolt off.
What do ya think? Shite or right?

Sorry should say that doing the above with out taking the nut off.

Do you fit new nuts to hold your wheels on everytime you have new tyres

True but wheel nuts aren't torqued up though

Supposed to be!

Theres a very good chance that you've got bolts instead of set screws which means the thread wont be long enough after you take the box section out so you'll have to buy new bolts anyway.

Don't worry about all these fancy, overpriced high tensile jobbies, just get some new stainless ones in those marine pre-packs
