I work in a manufacturing environment and keep all the weird anomalies that turn up in our hardware inventory. I have screws and carriage bolts with either half-formed or non-existent threads, keps nuts without the built-in washer, fiberlock nuts without the nylon, washers that didn’t get the center hole stamped through all the way, screws with off-center heads, Phillips screws with a ghost of where the Phillips hole should be, zinc-plated screws that only got half-dipped, a pop rivet that had the pin pressed cross-wise through the shank, and my favorite piece is a ball bearing that was packaged with a bee nestled inside the hole.

Nailed it.

Riveting!

/thread

I say attempt a friction weld.

I’d say this is fastenating but obviously it’s not!

Someone at the factory accidentally disabled hyperthreading. You only get a core.

You can’t just post lewds to Dull Men’s Club!

Put some threads on! Geeze!

Spiraled out of control

I didn’t think it was possible but you just put a new spin on screwing.

I tried to install a luggage rack on my car and the screw holes for the cover plates weren’t tapped, I feel your pain. Didn’t matter though because the cover plates didn’t align anyways so just left them off instead of tapping the holes myself

Look how dull that screw is, it’s perfect
