Can someone pls ID this (screw)driver bit (ie it's type name).
confirms this.
Ta. I did a wiki for this and found zillions of bits but not that one
- never heard of spanner bit before. It was actually the screwdriver version I wanted so maybe that's why.

I have not seen a slotted "nut" (actually more of a ring) since the 80's, maybe earlier - used to see quite a few kicking around off electrical appliances.
But I did have cause to file out a screwdriver 2 years back to take out a machine screw whose head needed the above profile. On a cheap fan heater. Ironically they did not think I should open it. I did think I should open it to blow out the fluff that was causing the element to run cherry red.
where I first encountered such a screw head.

I have always known the tool as a fork screwdriver. The nuts were commonly used to discourage people from fiddling with electrical appliances
Sometimes seen them sold as "snake eyes" security bits instead.
theTamper-resistant TORX screws pretty well too (I had "tamper resistant TORX plus" bits, but the "Tamper-resistant TORX" are different again)
holes in the top.
Snake eye is the term I have used. BTW Barnsley police station use a combination of a snake eye and a torx security screw on all of the switches/removable stuff in their cells. ie one of each on all things that can be unscrewed/removed.

They're also used by bicycle and motorcycle wheel builders - spoke nipples are slotted on the "bottom" for the initial build before trimming and tensioning - I used to use one in a yankee screwdriver for that very purpose, then made one on t'lathe from some 1/4" hex bar drilled all the way through so I could use a nelectric screwdriver.

No, those have circular pins.
