DIYers and repair folks, this pack of 100 copper threaded insert nuts is super handy for all sorts of projects. They're size M2.5 (metric), with a thread pitch of 0.45mm. Each nut is about 4mm tall with an outer diameter of 3.8mm, and they have a knurled exterior that helps them grip tightly when installed. They're made from copper, which offers good thermal conductivity and heat resistance. These are designed to be embedded into plastic or other materials – you can install them using heat (like a soldering iron), ultrasonic tools, or even mold them in during injection molding. They're perfect for creating strong, reusable threaded holes in electrical appliances, 3D prints, models, or any project where you need a solid metal thread in a softer material. The package comes with 100 pieces in a gold tone finish. Just a heads up: they're small parts, so keep them away from kids and pets. And always confirm the size (M2.5) is what you need before ordering. A versatile little hardware essential to have in your toolkit.
