What is the correct way to remove these? No slots, no heads per se. my guess is they were inserted with some sort of air tool. Special tool?? imgur.com/a/mWK4B2yFrom the Seeburg LPC480 I’m tearing down Thanks |

Hi Andy,
Attza "tamper proof screw"-- Yes a tool is made to remove them-- however it's been years since I saw one-- A large screw driver works---

I remember tamper proof screws like those from years ago. Drive-In Theatre speaker cases were assembled using them. I worked at several of those theatres (passion pits). People would remove the common slotted or Phillips screws and steal the internal speaker. When those tamper proof screws were used they just took the entire speaker by cutting the cords. Then cords with steel cables inside became available. About that time the entire Drive-In Theatre industry went away for most cities.

Hi Dave,
I first saw them when I was very young-- got a two week job, as a gopher, for company that built/repaired school bathrooms.
The stalls in the boy's room were assembled using them-- Boy's, being boys, always found a way to dis-assemble them ! lol Ron Rich

There's a "Security Screw" bit set that is sold... It may be in there.

That's a "prison" screw. Sometimes called a "one way" screw. This may help:

If you plan to reuse the screw, use a nice , new, sharp straight screwdriver and apply downward pressure while turning. If you get it started, and the head is small enough, chuck it in your drill and back it out. If you plan to replace the screw, use a cutting disc in a dremel to turn the ramps into a slot.
