This HELIFOUNER kit is a handy set of threaded insert nuts for all sorts of DIY projects, especially woodworking and furniture building. You get 60 pieces total: 20 each of three common lengths – 10mm, 15mm, and 20mm – all with a 1/4-20 thread (that's the coarse thread standard for many bolts). They're made from zinc-plated carbon steel, so they have decent corrosion resistance. The design includes a knurled outer surface and a flange – you drill a pilot hole in your material (wood, plastic, etc.), then use the included hex wrench to screw the insert into the hole. The knurling helps it grip and prevents it from spinning or pulling out. Once installed, they provide a strong, reusable metal thread in materials that would otherwise strip easily. Perfect for building workbenches, securing furniture legs, or anywhere you need a robust threaded connection. The hex socket makes installation easy with a standard Allen key. A must-have for any serious DIYer or maker's toolkit.
