Title: Tightening carriage bolts?
Post by: BerwynIrish on February 12, 2006, 10:04:11 am: I'm new to woodworking or any kind of construction and I'm can't figure out how these carriage bolts are supposed to work just by looking at them. I'm using them to attatch my monitor shelf to the inside of the cabinet, as recommended by many of the examples I've seen. First, you obviously pre-drill a hole large enough for the bolt to slip through, right? There's a hex neck on these bolts, so I assume you're supposed to insert the bolt into the hole up to the neck, but leave the neck exposed so you can grab it with a wrench for tightening purposes. But that would mean the end result is that the head *and* the neck are sticking out of the hole when you're finished tightening. That can't be right, because I'm sure it would look pretty crappy. What am I not understanding?

1) Buy a specially made bit for drilling square holes
2) Use a drillbit slightly larger than the diameter of the bolt shaft and crank down on the nut
3) Use a countersunk drillbit
4) Get a chisel and make your "square hole"

I use them on my wooden panels and they work fine. Just make sure that they have a square hole to sit in and it works pretty much the same as metal.

Good luck,
Rocky

I put all of my carriage bolts into an old cardboard box so that only the head was visible and spray painted about 5 light coats of Rustoleum on them. It worked perfectly and with enough coats, the paint hasn't scratched off yet.

Also, if you are putting the bolts into MDF, you don't need square holes. The material is soft enough that when you crank them down tight from the back the square part digs into the MDF until it sits flat.

I got mine from Happs. They say there is a minimum amount to order but I ordered way less than the amount and there wasn't a problem. I'm very happy with them.

Post by: Apollo on February 13, 2006, 06:04:05 pm: I have tried a number of different methods.

Stove or BBQ paint and then baking bolts in a hot oven works very well.

Powder coating also works well.
