Heat-Set Brass Inserts – M3 x 5mm x 4mm – (50 Pack)

Upgrade your 3D printed parts with M3 Heat-Set Brass Inserts, the professional choice for creating strong, durable, and reusable threaded connections. Instead of relying on printed plastic threads that can wear out over time, these premium brass inserts provide a secure metal thread capable of withstanding repeated assembly and disassembly.

Designed specifically for additive manufacturing, M3 Heat-Set Brass Inserts are installed using heat, allowing the surrounding plastic to soften and flow into the precision knurled surface. Once cooled, the insert becomes permanently locked into the part, providing exceptional pull-out resistance and long-term reliability.

Whether you’re building electronics enclosures, upgrading your 3D printer, assembling robotics, or designing functional engineering components, these inserts deliver professional-quality fastening every time.

Why Choose M3 Heat-Set Brass Inserts?

Unlike standard screws threaded directly into plastic, M3 Heat-Set Brass Inserts create a permanent metal thread inside your printed component. This greatly increases the strength of the assembly while preventing stripped threads and damaged parts.

The precision knurled exterior provides maximum grip inside the plastic, while the brass construction offers excellent corrosion resistance and thermal conductivity for quick, easy installation.

Compatible with most common printing materials including PLA, PETG, ABS, ASA, Nylon, PC, and other engineering thermoplastics, these inserts are an essential addition to any maker’s workshop.
