300 metal threaded inserts, plastic inserts (M2/M2.5/M3/M4/M5/M6/M8), threaded inserts and 3D printed inserts.

High-quality brass components: Threaded inserts and end adapters are forged from pure brass, offering superior resistance to rust, corrosion, and oxidation. They exhibit excellent thermal conductivity, are easy to install, and distribute stress evenly. Strong torque design: Nuts feature deep, uniform threads and an externally curved thread structure, significantly increasing friction with the substrate and ensuring a secure and stable installation. Easy integration with plastics or 3D printing materials guarantees reliable connections. Versatile: This kit includes multi-compartment storage boxes for convenient, practical, and efficient organization and storage. Available in various sizes to meet diverse application needs. Suitable for 3D printing, repair, and manufacturing of electronic components and automotive parts, and compatible with all thermoplastics.
