I also have a set of security bits from Maplin which covers just about
every other variation - useful for dismantling brown goods.

When you find one which has 5 slots radiating out from a central nipple,
let me know


Security TORX??

Nice try - almost but not quite.

These screws have straight slots not a bloated pentagram. They're used
by Sunvic to hold the case on actuator heads. I used to repair them and
ended up making my own screwdriver
