01AUTOMOTIVE REPAIR & SPECIALITY TOOLS
Precision Copper Threads for Embedded Hardware
A small but vital component in the world of fabrication, these brass inserts bridge the gap between soft substrates and hard metal screws. They sit quietly within your projects, ensuring that every fastener has a secure home.
Designed for makers working with 3D printed components, wood, or injection molded plastics, this set provides reliable threading where standard plastic threads might fail. It is the practical choice for anyone building durable, reusable structures.
02MATERIALS
High-Hardness Copper Construction
The core of each nut is formed from preferred copper material, selected for its inherent hardness and resistance to wear. This metallic composition ensures the threads remain sharp and distinct even after repeated cycles of tightening and loosening. The material’s natural properties contribute to a robust finish that stands up to mechanical stress without deforming or stripping.
04DESIGN
Knurled Surface for Grip
The exterior features a knurled texture, which increases friction against the inner wall of the hole during installation. This design detail helps prevent rotation while the part is being heated and seated. Once cooled, the knurling locks the insert in place, providing a stable base for screws that require significant torque or frequent adjustment.
DETAILS
Precise Threading and Dimensions
Each nut measures 0.40 by 0.45 by 0.50 centimetres, offering a compact profile suitable for detailed models. The internal screw thread is cut with accuracy, ensuring smooth engagement with standard screws. The golden hue of the copper contrasts subtly with black or white plastics, adding a touch of industrial character to functional assemblies.
