Faankiton 520PCS Heat Set Inserts for 3D Printing, Brass Threaded Inserts

• 🚕 【SUPERIOR DOUBLE TWILL KNURLING DESIGN FOR A SECURE HOLD】：Unlike standard straight knurling that can spin out under stress, our brass heat inserts with precision-machined knurled surfaces melt smoothly into plastic while providing superior torque resistance, excellent grip and stability. The strong mechanical bond helps prevent loosening, spinning, cross-threading and thread damage. Built to last for thousands of cycles
• 🛶 【HIGH-QUALITY BRASS MATERIAL FOR LONG-TERM USE】: Our knurled insert nuts are made from high-quality brass, offering excellent thermal conductivity, high hardness and resistance to deformation. They are rust-proof, corrosion-resistant and oxidation-resistant, with a smooth, burr-free surface, clear threads and a sturdy construction, making them suitable for long-term use
• 🏭 【520PCS COMPLETE METRIC SIZE ASSORTMENT M2-M5】：This heat inserts kit includes the most commonly used metric sizes：M2, M3, M4, and M5 threaded inserts. A complete selection for DIY projects, engineering prototypes, RC models, electronics enclosures, robotics and everyday 3D printing applications. Stop hunting for the right size in the middle of a project
• ⏳ 【NEAT STORAGE & EASY IDENTIFICATION】： No more searching through mixed parts. All knurled brass inserts are stored in separate compartments with clear size labels, making it quick and easy to find the correct metric insert during your projects. Perfect for makers, engineers and 3D printing enthusiasts. No more lost inserts or scattered parts
• 🌌 【PROFESSIONAL HEAT SET INSERT KIT FOR 3D PRINTING】：Upgrade your 3D printed parts with strong and reliable brass knurled nuts. Designed for PLA, PETG, ABS and other thermoplastics, these PLA inserts create durable metal threads that withstand repeated screw installation without stripping or cracking
• 🚤 【EASY INSTALLATION FOR BEGINNERS AND PROFESSIONAL MAKERS】：Insert the brass threaded insert into the hole and heat it with a soldering iron. After heating, press the brass insert into the part. Once the insert has cooled, screw in the screw. With ultrasonic heating or a soldering iron, the insert can be easily embedded into plastic parts
• 🔫 【WIDE RANGE OF APPLICATION】：Our knurled insert nuts are suitable for all thermoplastics, especially for 3D printers, electronic devices, laptop housings, automotive plastic parts, circuit board fixing, electronic components, and various plastic fittings
