Review on Yoohey 20Pcs Plated Fasteners Butterfly by Gary Generale

Well, entirely my fault, but I searched for "marine battery wing nuts" and Amazon listed these as the most recommended marine battery wing nuts, and since I was too lazy to check the screw size, i just assumed it would be correct. Obviously I was wrong. Marine sizes are either 5/16"-18 or 3/18-16. Problem with the products. LOL I just tossed them in my hellbox to use later. They were delivered very quickly and at a great price so am i all still give them 5 stars but note that they are not suitable for marine batteries.
