COPPER PHILLIPS HEAD SCREWS:
Copper and copper alloy Phillips head screws are specialized fasteners used in applications requiring corrosion resistance, electrical conductivity, and aesthetic appeal. We Conex Screws and fasteners are a leading manufacturers of Phillips head screws, Pan Phillips head Screws, CSK Phillips head Screws etc. in Copper, Brass and Silicon Bronze. Copper Phillips head screws are specialized fasteners manufactured from high-grade copper alloys, primarily used in applications requiring excellent electrical conductivity, corrosion resistance, and aesthetic appeal. These screws feature the distinctive Phillips cross-drive system, making them compatible with both manual and power tools while providing good torque transmission and reducing cam-out. Commonly manufactured from alloys like C11000 (ETP Copper), C26000 (Cartridge Brass), or C36000 (Free-Cutting Brass), they offer superior performance in marine environments, electrical installations, and decorative applications. Available in various head styles including countersunk (CSK), pan head, and raised countersunk, these screws conform to international standards such as ASTM, DIN, and ISO specifications. Their natural antimicrobial properties make them particularly suitable for medical and clean room environments, while their thermal conductivity benefits applications requiring heat transfer capabilities. Our Copper Phillips head screws, Copper Threaded fasteners and Inserts, Copper nuts , Silicon Bronze Phillips head screws, Brass Phillips head screws, Stainless Steel Phillips head screws are known for precision and high quality. We also offer SEMS screws in Copper, Brass, Bronze, Silicon Bronze with phillips head.
