I'm pretty sure the "uranium screw" is just a reference to the fact that the head of the screw appears to have split in two ("fissioned"), as opposed to a normal flat head screw that still has the edges connected. Sam887 (talk) 05:50, 16 January 2015 (UTC)
Just a shot in the dark here, but a company that sells uranium ore and radiological equipment happens to also sell screws for one of its Geigers that look just like the screw cross-section in the comic.  Conqu2 (talk) 06:01, 16 January 2015 (UTC)
I was wondering if the "uranium screw" was referring to the Demon Core -- two hemispherical domes that Louis Slotin was holding apart with a screwdriver. Then I remembered the Demon Core was plutonium, not uranium. 188.8.131.52 06:49, 16 January 2015 (UTC)
I think the be was going for apple's pentalobe screw with the 5 ponted star
I don't think the uranium screws are named for their use in stuff to do with uranium, as I have both seen and used screws that look like that before. It's basically a flat head screw whose divot extends all the way across the face of the screw. I agree more with the previous commentor who notes that the screw looks like it has fissioned. 184.108.40.206 06:34, 16 January 2015 (UTC)
An actual rivet is neither a screw nor a bolt; it's a fastener that is placed and then has one end plastically deformed -- traditionally by a rivet gun, but more often in smaller sizes by some sort of press or clamp. (Pop rivets are hollow, and are deformed by pulling a cone-sheaped wedge into the open end of the hollow core.) There's no way to remove one except to destroy it (drill it out or cut one end off). The item pictured could also be the head of a carriage bolt, but that's no help if you can't get at the other end of the bolt. Randall is slightly pessemistic, though: there *are* some "security" screws and bolts that use a slightly-elliptical domed head that's hard to tell from a rivet; they can be unscrewed, but only with a matching slightly-elliptical socket. 220.127.116.11 06:35, 16 January 2015 (UTC)
All of which can be removed by a sonic screwdriver. Totally a real thing.
Could the "cursed -1" be a Nethack reference? I don't know if Dungeons and Dragons has the "blessed/uncursed/cursed" status, but in Nethack cursed items with negative enchantments (denoted "cursed -whatever") are a pretty common occurrence. 18.104.22.168 07:31, 16 January 2015 (UTC)
In Nethack, Cursed objects cannot be removed. Seems appropriate. At first I thought it was a pozidrive screw head. Posts on the fission screw head: where have you seen screws whose divot does *not* extend across the head?
Kreuiter (talk) 08:03, 16 January 2015 (UTC)from wikipedia: Louis Philippe Joseph d'Orléans (13 April 1747 – 6 November 1793) commonly known as Philippe, was a member of a cadet branch of the House of Bourbon, the ruling dynasty of France. He actively supported the French Revolution and adopted the name Philippe Égalité, but was nonetheless guillotined during the Reign of Terror
I don't think it is specifically a reference to Nethack as a lot of ol games (both video and tabletop) use the mechanic of non removable cursed objects. It is common enough in my opinion that we could argue about until we are blue in the face and get nowhere.
--22.214.171.124 08:28, 16 January 2015 (UTC) uranium screw may be a reference to Louis Slotin, who died when he was using a screw driver to seperate two halves of a plutonium sphere as part of a science demonstration, and triggered a large burst of radiation when his hand slipped.
I'm thinking it might benefit the article to include a place in the wikitable for the correct term for each drive socket. Of course their are not correct terms for each of them. Not to mention rivets and Phillip's heads don't even have drive sockets. 126.96.36.199 09:04, 16 January 2015 (UTC)BLuDgeons
If you suggest cursed-1 is because if misuse - I in first place thought of  as the cursed one - because Philipps and Pozidriv are slightly incompatible and causes damage. 188.8.131.52 09:09, 16 January 2015 (UTC)
