Screw head identification

[stevepbuk]

Hi

Can anyone identify what type of screw head this is. It looks like a Z shape. It's on a leaf blower.

Thanks

Steve

Looks vaguely like a security screw (you can tighten but can't unscrew) but that would be a bit nonsensical on a leaf blower unless they really don't want you to get inside it.

Agreed: security screw. You could try using a pointed punch to move it anti-clockwise. I'd replace it with a standard screw.

Is it my tiny screen or does the slot on that clutch screw not appear uniform, I.e wider at the bottom ?
Can't understand why that type of screw should be used there!
