Grover DIN 7980 M18 A4

Grover is a small simple metal fastener that can withstand heavy shock loads and act as a stop.

Grover DIN 7980 differs from DIN 127 in the shape of the cut. It is square, as opposed to rectangular in 127. Therefore, it is slightly smaller in width and lighter in weight. This type of fastening is suitable for a screw connection, that is, when a screw is screwed into a part, without a nut and a grover must be placed under a cap, DIN 127 would be wide for such caps and would only be used for 50% of its locking capabilities. Whereas DIN 7980 fits perfectly on the outer edge of screw caps with smaller widths than nuts or bolt caps.
