M3 x 10 Brass Threaded Inserts Nut

M3 x 10mm Brass Threaded Insert Nut

Heat-set/press-fit brass threaded inserts with a 3mm internal thread diameter and 10mm body length. Precision-machined from high-quality brass, these inserts create strong, durable, and reusable threads in materials that don’t hold screw threads well on their own — such as 3D printed parts, plastic enclosures, wood, and soft metals.

Once installed, the knurled outer surface locks firmly into the surrounding material, letting you insert and remove M3 screws or bolts repeatedly without stripping the threads.

Key Applications

• 3D Printing: The most common use — melt these into PLA, PETG, or ABS prints using a soldering iron to add strong, reusable M3 mounting points. Ideal for enclosures, brackets, and functional prototypes that need to be assembled and disassembled.
• Electronics: Provide secure, long-lasting mounting points for PCBs, panels, and enclosures.
• General Fabrication: Add durable threaded connection points to wood or soft metal assemblies.

Why Choose Brass Threaded Insert Nuts

• Reusable threads — no more stripped screw holes in plastic or printed parts
• Corrosion-resistant brass construction for long-term reliability
• Knurled body for maximum grip and pull-out resistance
• Compatible with standard M3 screws and bolts
