Rhino Rigging on Instagram: "Mounting a harken winch on a mast mounting base. Know your winch hardware =Harken - metric hex heads Or SAE Allen head. If you tap the surface to make threaded holes. Then you have to use the Allen heads. If you drill and put nuts on, then you must use Metric, as the winch has captive bolt holders, but only for metric. Comment ? If you don’t know what I’m talking about and I’ll explain more. Otherwise comment how you do it. . . #sailing #riggerslife #hardware"
