Having seen those “special” bolts funny sketches over the years, I have always fancied having a 3D version.

I had a bit of spare time, so drew up all the bolts and 3D printed them.

I’ve put some in a frame for the shed and another to take to work for my office.

It’s a simple thing, but makes me happy!

Seen these before but still made me laugh. However, when I looked at the bolt for a countersink drilled too deep (middle row, second from right) I realised that I’d recently come across exactly that bolt in real life. Look on the site for the Australian tank museum where they restore WW2 armour. Apparently, armour plate was bolted on using bolts with a long tapered head fitted into a tapered hole to finish flush with the surface of the armour. Standard headed bolts. when you hit them with an anti tank shell have an annoying habit of shearing off the head and the rest of the bolt gets fired into the tank at great risk to the crew. A tapered head bolt just seats more firmly into its hole.

Sometimes, life really is stranger than fiction.
