Generic 200Pcs M3X4mmX5mm Knurled Brass Heat Set Inserts, Threaded Embedded Nuts for 3D Printing, DIY Electr

Product description

Our M3 knurled brass heat set inserts are professional fasteners specially designed for 3D printing makers and electronic assembly enthusiasts.

The package contains 200 pieces high-quality solid brass threaded nuts, adopting double spiral knurled outer structure to maximize grip force with thermoplastic.

High-purity brass material delivers excellent rust-proof, heat-resistant and wear-resistant performance, solving the common pain point that pure plastic threaded holes are easy to wear and slip during repeated disassembly.

Each insert features precision machined standard M3 inner thread with smooth surface without burrs, perfectly matching all M3 metric screws.

Easy to install via heat insert iron tips

when heated and pressed into 3D printed plastic holes, the melted plastic wraps around the knurl texture to form permanent tight connection, anti-loosening and anti-vibration even under long-term mechanical load.

Versatile for multiple DIY and industrial scenes: 3D printing prototypes, electronic equipment enclosures, drone &amp

robot frames, household plastic parts, notebook shells, model toys and small mechanical assembly.

With a large quantity of 200pcs per pack, it can fully meet your long-term production and project needs, a cost-effective durable fastening solution for all plastic assembly work.

Premium Solid Brass Construction for Long Service Life Made of high-purity solid brass, anti-rust, corrosion-resistant and high thermal conductivity, won’t deform under repeated disassembly.

Effectively prevent plastic thread slipping or stripping for your 3D printed components.

Dual-Side Knurled Anti-Slip Design for Firm Embedding Double spiral knurl outer surface greatly increases friction with plastic.

After hot insertion, the nut locks tightly inside plastic shells, anti-vibration and won’t fall out under torque load.

Precision Standard M3 Internal Thread, Universal Compatibility Uniform precision machined M3 female thread, smooth burr-free inner hole, perfectly match
