Tackling a DIY project and need to add strong, reliable threads to soft materials? This 20-piece assortment of threaded inserts is your new best friend. These are self-tapping inserts, meaning you basically just drill a hole and screw or drive them in - super easy. They're made from sturdy carbon steel with a zinc plating to resist rust, so they're built to last.

The kit gives you a great range of sizes to cover most jobs. You get inserts with inner threads (the hole the bolt screws into) from M2 all the way up to M12, with matching outer threads to grip the material. For example, you've got Inner M2 x Outer M4.5, Inner M4 x Outer M6.5, up to the big one: Inner M12 x Outer M16 (which is 22mm long). They're perfect for reinforcing wood (like oak, cherry, or maple in furniture and cabinets), plastic, or even softer metals.

Why use them? They create a much stronger connection than just screwing into wood or plastic directly, and they prevent stripping. Great for furniture assembly, automotive repairs, electronics, machinery, or any hobby project where you need a solid threaded hole. The package comes with 20 pieces covering various sizes, so you'll likely have the right one for the job. Super handy to have in your toolbox!
