DIYers and woodworkers, listen up – these threaded inserts are super handy for making strong, reusable threads in wood. You get 100 pieces in the pack, each measuring 5/16-18 internal thread and 20mm long. They're made from alloy steel with a zinc finish, so they're tough and resist rust. The hex-flush design means you can drive them flush with the wood surface using a standard hex key or wrench. They've got broad external threads that really bite into softwood, plywood, or MDF, giving you way better holding power than just screwing directly into wood. Perfect for assembling furniture, attaching drawer pulls, mounting hardware, or anywhere you need a solid metal thread that won't strip out over time. Way better than using regular nuts or T-nuts in many cases. They're easy to install – just drill a pilot hole, screw the insert in, and you're done. Great for fixing wobbly furniture, building custom pieces, or any project where you want strong, clean fastening points. Keep a pack in your workshop; you'll find uses for them all the time.
