Brass Insert M3x15 for 3D Printer Parts

Brass Insert M3x15 for 3D Printer Parts

• The Brass Insert M3×15 is a precision M3 heat set insert made to create durable metal threads inside plastic and 3D printed components.
• Instead of relying on screws biting directly into soft materials, this brass threaded insert provides strong M3 internal threads that allow repeated assembly and maintenance without stripping the host part.
• Manufactured from high-quality brass, it offers excellent corrosion resistance, high thermal conductivity for heat-set installation, and long service life.
• The knurled outer surface is designed to lock into plastics, reducing rotation and improving pull-out resistance after installation.
• With a 15 mm length, this Brass Insert M3x15 provides deeper engagement than shorter inserts, making it ideal for structural printed parts, thicker brackets ,mounts, enclosures, and assemblies where higher holding strength is required..
• These inserts are widely used in 3D printer parts, robotics, electronics housings, and plastic enclosures—anywhere you need reliable threaded fastening in plastic with professional durability.
