Sounds like a tri-wing driver. They sell these at McMaster-Carr. Look
under tamper resistant drivers.

Trying to fix a small electric heater held together with security
screws.

The screws have a recessed triangle in the center; sort of like a
square drive screw, but it's a triangle.

Do these screws have a name?
