Shakeproof Washer (Internal)
Shakeproof washers have serrated edges around the washer to help hold it in place by gripping the surface. This is especially useful in high vibration settings.
Also referred to as star lock washers, or tooth lock washers, shake proof washers are available with the serrations on the inside or the outside of the washer, depending on what type of screw it's being used with.
Standards: DIN 6797; ASME B18.21.1
