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?

You can remove them with a left-handed drill bit and a variable speed
reversible drill. Replace with normal sheet metal screws, or put them
back using a normal drill bit.

You can buy a left-handed drill bit at your local full-service hardware
store.
