Metric Hex Jam Nuts (DIN 439), A2-70 Stainless
Metric Hex Jam Nuts
Metric hex jam nuts are thin metric hex nuts. They have coarse and fine machine screw threads, like metric hex nuts, but their reduced thickness results in a reduction in strength. They are used with small machine screws to save space or to "jam" against another nut to create a locking action.
