KYOUJIN Hex Head Metric Screws manufactured to ISO 4017 standards are ultra-high-strength engineering fasteners designed for applications requiring exceptional mechanical performance, dimensional stability, and weight reduction. Manufactured from KYOUJIN, a carbon fiber polyamide, these screws offer strength characteristics approaching those of light metals while retaining the corrosion resistance and nonconductive properties of advanced engineering polymers.
The hex head design enables secure installation using standard spanners and sockets, providing excellent torque transmission and reliable clamping force in demanding assemblies. KYOUJIN hex head screws are widely used in aerospace, motorsport, robotics, semiconductor equipment, automation systems, and high-performance industrial applications where minimizing weight without compromising strength is critical.
Combining outstanding stiffness, fatigue resistance, and thermal stability with excellent resistance to chemicals and environmental exposure, KYOUJIN fasteners deliver long-term performance in applications where conventional plastic fasteners may lack sufficient strength and metal fasteners may add unnecessary weight.
