Brass Insert M4x12 for 3D Printer Parts

Brass Insert M4x12 for 3D Printer Parts

• The Brass Insert M4x12 is a precision M4 heat set insert designed to create durable, reusable threads in plastic and 3D printed components.
• Instead of relying on screws cutting into soft material (which can strip over time), this brass threaded insert provides strong internal M4 threads for reliable fastening in printed parts and lightweight assemblies.
• Manufactured from high-quality brass, it offers corrosion resistance, long service life, and excellent heat conductivity for heat-set installation.
• The knurled outer surface is engineered to lock into the surrounding plastic, helping prevent rotation and improving pull-out resistance.
• With an 12 mm length, this Brass Insert M4x12 is ideal for compact parts where you need strong metal threads without excessive depth.
• The insert is well suited for 3D printer frames, mounts, brackets, and mechanical parts that use standard M4 screws.
• It’s also commonly used in electronics housings, robotics assemblies, and DIY engineering builds where plastic parts need professional-grade threaded connections.
