Review on 🔩 LQ Industrial 30pcs 5/16"-18 Painted Furniture Screw-in Nut: Zinc Plated Bolt Fastener for Wood Furniture by Ron Kishore

I bought 30 pieces and I am very happy with them. You won't believe how many ways you can think of using them. My joinery is in a nearly watertight basement that's 100 years old. Whenever I build a new bench or stand I use this and a screw to make the legs adjustable and waterproof. They are excellent for making jigs and other tools. An advice. Because of their design, they seat themselves when installed in front of panel products. However, when inserting into the butt, be sure to drill a slightly deeper hole than necessary and use some sort of countersink to make room for the expanding head. Otherwise you will likely cause a split.
