This is fantastic, thank you!

If #AvE was in the fediverse he'd love this, I think.

There's been times I really could have used a telescoping bolt.

@GustavinoBevilacqua Second row, second column doesn't look outright useless?

@loke

This one?

It looks like a screw for a 30° countersunk hole, which is the one with the most sense, for thick parts.

Sometimes I'd be happy to have screws like this one!

@n_dimension @GustavinoBevilacqua Some of them do look usable.

The tapered screw is just an NPT thread with a more aggressive angle for example

@GustavinoBevilacqua Brilliant! I have a paper diagram that contains all these gems, but have never seen a physical version before.

@GustavinoBevilacqua Also have a scan of a really old spoof British Standard for Garden Gnomes. There is still gold out there to be found!!

@GustavinoBevilacqua this is the real life equivalent of self sealing stem bolts!

@GustavinoBevilacqua this thing implies that there is a "screw or butt-plug" questionary somewhere.

[bodling@deacon.social]

@GustavinoBevilacqua I could use a couple of those

[gustavinobevilacqua@mastodon.cisti.org]

@Bodling

Yeah, some of them are smarter than they look.

[dereisenhofer@metalhead.club]

@GustavinoBevilacqua They get better and better!

@GustavinoBevilacqua I have an unreasonable and frankly unfortunate desire to replicate this.

[adventure_tense@mapstodon.space]

@GustavinoBevilacqua I believe we use a few of these at work. :-)

[thorsten4future@climatejustice.social]

@GustavinoBevilacqua Tahnks to #3Dprinting it's now so much easier to make these :)

@GustavinoBevilacqua my brother and his fellow apprentices once found a phillips screw with no thread which they promptly deposited in the material room, just so they could send first-years to fetch a phillips nail.

This inspired them to spend several days on the attempt of bending a screw into a 90° angle, just for pranking first-years with an "angle screw" :-D

@danielaKay

To set a 90° screw you must make the hole with a 90° bit
