Review on Stainless Threaded Quantity Bolt Dropper by Keith Barra

I use when changing boat trailer berths. I hate it when lousy wooden studs come loose after a few years, so I decided to find a more reliable solution. I clamp the new boat moorings in place, drill the correct size hole (3/8 in this case) from the bottom push up bracket up through the mooring board and out the top of the mooring. Take a 1 inch spatula and make an indentation in the top hole where the t-nut will sit. Drive in the T-nut with a hammer. Cover the bunks with your desired bunk material and bolt the bunks on by threading a 3/8 stainless steel bolt into the t-nut. - Walnut More work, but I've never had trouble sleeping since using this method.
