,Brass insert nut for CNC
Straight Knurl Brass Insert Nut is a professional anti-slip embedded threaded fastener optimized for plastic injection molding and hot melt installation. Unlike traditional cross knurl nuts, this brass insert nut features a vertical straight knurl outer grain design, providing excellent anti-rotation and anti-pulling performance.
Manufactured from high-quality brass material, the product offers outstanding corrosion resistance, oxidation resistance, and stable mechanical properties. It can be firmly embedded in various plastic shells and components, providing durable, high-precision, and non-loosening threaded connection points for electronic products, household appliances, and plastic molding accessories.
The outer wall features uniform vertical straight knurl texture processed through professional precision rolling technology. This straight grain structure enables complete infiltration and tight wrapping of plastic materials during injection molding and hot melt embedding, effectively resisting torsion and pulling forces while preventing slipping, rotation, and falling off during long-term use.
Manufactured from premium high-purity brass raw materials, these insert nuts maintain stable metal toughness and hardness. They resist rust and oxidation in conventional indoor and humid environments, featuring excellent anti-corrosion performance and good high-temperature resistance without cracking or deformation during processing.
Internal threads are formed by precision tapping process with standard tooth pitch, complete tooth shape, and smooth inner walls free of burrs or broken teeth. They perfectly match standard screws of corresponding specifications, enabling smooth assembly and disassembly while maintaining stable locking force after repeated use.
With standardized overall dimensions and precise tolerance control, these straight knurl brass nuts offer high fitting accuracy. They support both injection molding pre-embedding and post hot melt pressing installation methods, ensuring high consistency in batch production to improve efficiency and reduce assembly failure rates.
