carriage bolts

Anonymous-0 · Jan 28, 2014

replacing a deck on a 1936 International stake bed truck. How is one supposed to keep these carriage bolts from spining in their place when the nuts have rusted up et.? hate removing these old carriage bolts. Should they be installed in undersised holes? they seem worse in pine they just spin in place and need to be cut off etc. What am i doing wrong? Thanks

They make galvanized "anti-spin washers" They have a square hole to fit the shoulder on the carriage bolt, and little spurs that bite into the wood to keep them from spinning.

I cut them off with a Sawzall.

Many decades ago when I was pounding on the bearings on a NH 460 Haybine, a fellow suggested I use a flame wrench.
With a wooden trailer deck of mine I cut, ripped, busted, and broke the old wood off, then cut the bolts off.

Torch and a sprayer full of water...and a bucket of water just in case.

try using a nut cracker on the nuts if you have the room--works good up to about 1/2 diameter

If you're talking about removing the old ones (vice keeping the new ones from spinning as I obviously assumed...) I find that an air chisel works about as good as anything.

here is a good example of why I love this website. Never saw these before, but wish I had. They will come in handy for future projects. thanks

If you plan on redoing wooden sides on a truck, do whatever you want to get the old stuff apart, maybe use fawteen's shark washers, but I have found it worthwhile to use acorn nuts on sides that you gotta work around. Any exposed 1/4 or 5/16 bolt ends act like a magnet, to tear up shirts and pants and occasionally skin or knuckles !

Are you using a air wrench or a socket wrench on them? It helps a lot of the time if you have someone put pressure on the head with a wood 2x2 while you loosen them to help keep them from ever starting to spin. Dosent work all the time but helps some.

I do not use carriage bolts. Methods of removal has been pretty well covered and I have hacksawed a screwdriver slot in the head. Why go through that again? If I wont a smoothe surface, I counter bore and use a hex head screw.
I might add that I have received complements from more then one person about my trailer boards.

Those work well but most of the time my luck has it that the wood has rotted away just enough that those spin also LOL

I've found that after "spinning" them there is often enough"slack" that you can put a visegrip on the nut vertically and rock back and forth and break them.

Areo

In addition to the other ideers, you might try tightening "em with an air wrench......and twisting "em off.

Yeah, you just have to go to a place that has a GOOD selection of fastners. Not the Slowes

If there not to rusty I put a slot in the head with a angle grinder with a cutting wheel. Then use a large screw driver. If that doesn't work use the grinder to cut the nut off. Small angle grinders are one of the most useful tools there is!

These are new to me. You made my day!

Sometimes when INSTALLING them they round out their holes and start spinning even before I have drawn the nut all the way up and I can't get them tight.

Try a BHCS (button Head Cap Screw) which will stick up about the same as a carriage bolt and not be a hazard to catch anything on. Go to a Bolt Supply place or online and order by the box of 100.

Your welcome, folks. I "discovered" them when I worked at a building supply place.

We were the smallest branch of a 10 branch operation, and we stocked them. One summer I was building a small deck for my daughter and needed a handful. The HOME OFFICE branch didn't stock em...

Glad I could contribute.
