Ohio Dem

I have a question for the smartest people on the internet.

My brother paid a visit today and asked me a question. He, for the life of him, couldn't think of a word, and I wasn't able to help. I googled it, but I couldn't find the answer.

A carriage bolt requires a square hole in the wood, metal, or whatever. What is the name of the process that produces that square hole?

I'm cross posting this in the Lounge.

In metal it would be punched. In wood, ya just tighten up the bolt and it will make it's own square OffWithTheirHeads Feb 2012 #1

"setting" is what it's usually called for wood.

Edited to add: Which is an awfully fancy name for a process that's best described as "Smack it with something until it stops turning".

Poster 1 is correct that you don't need it in wood: http://www.democraticunderground.com/1158529#post1

I had bad luck forcing carriage bolts into a thick aluminum sheet. I would tighten the 1/4-20 nut, then break off the bolt. I had to redrill the hole a few times, and progressively larger, until the square shaft was just barely an "interference fit" in the hole.
