  • \$\begingroup\$ When I came across one of these recently, I simply took an old screwdriver and used my Dremel to cut off the original tip and then grind a new triangular tip. The fact that the handle had six sides made it easy to get the angles right. It only took a few minutes, and it worked like a charm. \$\endgroup\$ – Dave Tweed Feb 14 '14 at 13:56

  • \$\begingroup\$ Dave, Your solution sounds quite nice. In other comments I found right answer for the head name, but prices are quite high for opening 4 screws. I'm going to follow Your idea, after opening i will put normal screws. Tank You \$\endgroup\$ – user37190 Feb 14 '14 at 14:17
  • \$\begingroup\$ Those look like the screws in a Nintendo DS. You can get one of the DS TriWing screwdrivers for US$1. Google "nintendo ds screwdriver". You might try that. \$\endgroup\$ – mikeY Feb 14 '14 at 16:55

Looks like a triangle headed screw to me. I had to get a set of drivers for these a while ago. In this set are TA18, TA20, TA23 and a TA27 - Triangular Allen key perhaps?

  • \$\begingroup\$ You have right, it's looks just like mine. I will try to make myself that screwdriver if not work... i will have to measure somehow this screw and order this set. Regards \$\endgroup\$ – user37190 Feb 14 '14 at 14:19

Looks like either a TA ("delta") or TP3 drive.

Edit: On closer examination (on a real monitor) the sides of the triangle appear to be straight, which means it's a TA as pattyhoyts suggested.
