• STURDY & DURABLE THREAD INSERTS These threaded inserts made of high quality C3640 brass are characterized by excellent corrosion resistance, thermal conductivity and durability. They have remarkable resistance to breakage and deformation.
• EASY TO USE Knurled threaded inserts can be easily embedded into tunnels or through holes by heating or ultrasonic heat process and provide a reliable and safe method of fixing parts in 3D printing projects.
• Secure Grip with Easy Application The surface of the 3D printed press nut with high precision and clear threads ensure stability and reliability and prevent the thread from slipping off during rotation. The knurling at 45 degree angle greatly increases torque and tensile strength and ensures a secure attachment.
• Wide application: the knurled nuts are suitable for all thermoplastics, including PLA, PETG, ABS, PPS, PP and others. Whether used in 3D printed objects, electric injection moulding machines, injection moulded plastic parts, plastic housings for motor vehicles or laptop cases, their versatility ensures compatibility with a wide range of materials.
