whilst slotted fastener heads are more at risk of cam-out compared to much more present-day styles, their simplicity of use and simplicity make them a go-to choice in apps wherever Extraordinary torque is just not a Major worry.
There’s also a triple sq. with 3 Robertson’s squares, generating a 12-issue star. Triple squares are most often used when You'll need a significant volume of pressure devoid of stripping the screw. You’ll see them totally on internal auto parts, like drivetrain factors.
