About this item

  • 👨‍🔧【High Quality Material】: Our Lukaisen knurled nuts are made of brass with high strength and hardness properties. To ensure excellent corrosion resistance and thermal conductivity, they can withstand temperatures over 300°C / 572°F and can easily withstand the high temperatures generated by the plastic thermoforming process. This means that each insert nut is long-lasting and easy to use. When the insert nut is no longer needed, it can be reused by carefully removing it from the pressure element.
  • 👨‍🔧【Precision Craftsmanship】: Lukaisen's knurled nuts' high precision and crisp threads ensure stability and reliability, preventing thread slippage during rotation. The 45-degree angle of the thread knurling dramatically increases torque and tensile strength and ensures a more secure fastening. Recessed nuts feature a guiding element that eliminates the need for countersinks or grooves, making your work easier and more efficient.
  • 👨‍🔧【Best 3d Printed Parts】: Threaded inserts designed to retrofit 3D printer parts for Anycubic, Creality or Prusa printers. All parts are printed with 100% infill. Therefore insert nuts can easily be ultrasonically or thermally (soldering iron) embedded in bags or through holes, or they can be installed during the injection molding process. Since the inserts have conduction valves, there is no need to backdrill and countersink the holes.
  • 👨‍🔧【Suitable For All Kinds Of Plastics】: Lukaisen knurled nuts have 180PCS, containing 5 types of sizes - M2 M2.5 M3 M4 M5. Each type of size is the most commonly used in daily life. The insert nuts are suitable for all thermoplastics. For example, knurled nuts can be used for PLA, PETG, ABS, PPS, PP and other plastics. They are also suitable for circuit board assembly and electronics. Once the plastic around the brass sleeve has cooled and hardened, the threaded sleeve is held firmly in place.
  • 👨‍🔧【Easy To Use And Store】: All knurled nuts are stored in a reinforced divider box, each knurled nut is placed according to the corresponding size to prevent mixing during transportation. The box is also labeled with clear sizes on both sides to help you quickly find the type you need, which greatly improves work efficiency.

Nice set with some variety of sizes to fit different applications. I appreciate that for each size they also list the recommended hole size. Without that measurement a hole too small can result in excess melted plastic melting into the insert requiring cleanup with an exacto knife, or a too large hole reducing the strength and risking the insert coming loose.

These are well constructed and all of them I measured with calipers were to spec. They're well organized in a compact case, and there's an excellent variety for workshop applications present and future. I'm sold! Everything is as it should be, no burrs or sharp edges, and easy to identify and find the right part. Not sure what else there is to say - they're exactly as I hoped they'd be.
