Camerock

These nuts come in 9 different sizes and one side on each nut has square teeth that allow it to be mated to another one so as to allow vertical slip-free nut stacking and easier placing for those larger placements that don't take smaller numbers. All sizes are tapered. Sizes 1-2 withstand 3kN, sizes 3-4 withstand 8 kN and sizes 5-9 withstand 11kN
