Need to fix some wobbly furniture or build something sturdy? This LBY kit has you covered. It's a 25-set assortment of 1/4 inch threaded insert nuts and matching bolts. The nuts are 13mm long with a flanged hex socket design, so you can screw them into pre-drilled holes in wood easily. The bolts come in five handy lengths: 1-1/2 inch, 2 inch, 2-1/4 inch, 2-1/2 inch, and 3 inch – five pieces of each. They're all made from carbon steel with a zinc-plated silver finish to resist rust. Super handy for reinforcing cribs, beds, tables, chairs, workbenches, or any wood project where you need a strong, threaded connection. The hex drive makes installation simple with a standard Allen key. No more searching for the right hardware – this kit has the basics ready to go. Just grab your drill and get to work!
