Need some sturdy tee nuts for a project? This BCP679 pack gives you 25 zinc-plated steel, four-prong tee nuts. The size is 3/8-16 (that's the internal thread size) by 7/16 inch. The zinc plating gives them decent corrosion resistance for indoor use or in dry environments. Tee nuts are great for woodworking, furniture assembly, speaker building, or any DIY project where you need a strong, threaded insert in wood or particle board. The four prongs bite into the material to prevent spinning when you screw a bolt into them. They're from BCP Fasteners, a small family-owned company in Tennessee focused on quality. Keep a pack in your workshop – you'll be surprised how often you need them. Perfect for when you're building something that needs to be taken apart and put back together securely.
