ISO14579 Stainless Steel Torx Socket Head Cap Screw Supplier In China
Ningbo Teng Qi Fasteners Co., Ltd. is a professional manufacturer and supplier of ISO 14579 stainless steel hexalobular (Torx) socket head cap screws, specializing in high-precision fastening solutions for global industrial applications. With extensive experience in fastener production, we focus on delivering consistent quality, stable performance, and reliable supply for international customers across multiple industries.
Our products are manufactured in strict accordance with ISO 14579 standards, using high-quality stainless steel materials such as A2 (304) and A4 (316). Compared with traditional hex socket designs, the hexalobular (Torx) drive system defined by ISO 10664 offers improved torque transmission and reduced cam-out risk, making it particularly suitable for high-torque and automated assembly environments.
Production is supported by advanced cold forming technology, precision tooling, and comprehensive quality control processes. We ensure accurate dimensional conformity, stable mechanical properties, and precise thread tolerances in accordance with ISO metric standards. Our product range covers sizes from M2 to M20, meeting the needs of a wide variety of industrial applications.
To meet different environmental and performance requirements, we provide stainless steel grades in accordance with ISO 3506, including A2-70 and A4-80, along with passivation and optional anti-galling surface treatments. These enhancements improve corrosion resistance and assembly stability, especially in demanding operating conditions.
