Product Details
✓【Threaded Inserts】Crisp, high-accuracy threading prevents slippage, while 45° knurling boosts torque resistance and pull-out strength for rock-solid fastening.
✓【Premium Heat Set Insert】 – Machined from top-grade brass for superior heat transfer, corrosion resistance, and long-term durability; withstands temperatures up to 572°F / 300°C without cracking or deforming.
✓【Effortless Installation】Installs easily by heating, ultrasonic insertion, or during molding; even a basic soldering iron can seat these inserts cleanly into 3D-printed parts.
✓【Compatibility】Ideal for all thermoplastics (PLA, PETG, ABS, PP, PPS, etc.) and electronics applications—from 3D prints and injection-molded components to automotive housings and laptop shells.
✓【Ready-to-Use】Supplied in a sturdy, compartmentalized storage box to keep sizes separated, fully tested for quality— so you can grab the right insert and get straight to work.
