“Great product for our glass pool fence panel project, used with countersunk head stainless M10 bolts.
One point, these nuts can have a tendency to bind on the bolt and possibly cause spalling. So plenty of lube on nut and threads and don't rush to tighten the nuts, use manual gear, or set you driver to operate a quite a steady low speed. But it's great to know these locknuts won't need constant checking that they have maintained their tension on an elevated deck railing.”
