- Partially threaded shank provides optimal grip length while reducing weight and material usage
Professional Applications & Engineering Value
Engineered for critical industrial applications, these socket head cap screws deliver exceptional performance in machinery assembly, automotive systems, and precision equipment. The black-oxide alloy steel construction combined with Class 3A UNRF fine threads addresses common challenges of vibration loosening and thread stripping in high-cycle operations. The partially threaded design ensures maximum clamping force where needed while the hex socket drive enables secure installation in space-constrained environments. This combination of high tensile strength and precise thread geometry provides engineers with a reliable fastening solution that maintains integrity under extreme mechanical stresses, reducing maintenance frequency and downtime in production environments.
Specification Summary & Compliance
Manufactured to exacting standards with Class 3A thread fit and UNRF fine thread specifications for superior dimensional accuracy. Complies with ASTM A574 manufacturing standards for socket head cap screws, ensuring consistent quality and performance. Meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental compliance requirements, making these screws suitable for global industrial applications with strict regulatory standards.
