stainless steel nut keeps

Stainless steel nut keeps

Our customer wanted a method to stop the nuts from spinning when working on his boat engine as it was hard for him to reach under the engine on the boat and attach a spanner onto the nuts. we designed and produced these stainless steel keep plates.
made form 2mm thick 316 grade stainless steel we water jet cut two plates one with the hole centers on, the other with half nut shapes on. we then precisely located the two plates and welded them together.
now our customer can use these as a washer plate that fits across both bolts on the engine mount and then when he tightens the bolts from above the nyloc nuts will not turn as they are locked into the half hexagon shape in the lower plate.
