• High mechanical strength with a Rockwell B55 hardness and 40,000 psi tensile strength for reliable performance under load
• Secure and flush installation enabled by the smooth, low-profile hex socket head requiring only a 4mm driver
• Consistent and reliable threading with a Class 6g fit M6x1mm coarse thread for easy assembly and vibration resistance
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe use in regulated markets
• Optimized for automated assembly with a standard right-hand thread and smooth head texture for efficient production lines

Professional Applications & Engineering Value

This M6 shoulder screw is engineered to solve critical alignment and wear challenges in precision applications. The 360 brass material offers excellent machinability and inherent corrosion resistance, making it perfect for electrical components, machinery, and assemblies exposed to moisture or corrosive agents. The precise shoulder fit acts as a built-in pivot or axle, eliminating the need for additional spacers or bushings, which reduces parts count and assembly time. The hex socket head provides a clean, low-profile finish while allowing high torque application without stripping. Its Class 6g thread ensures a secure fit in industrial settings, preventing loosening from vibration and maintaining positional accuracy in moving parts.

Specification Summary & Compliance

This metric shoulder screw features an M6x1mm coarse thread with a Class 6g tolerance fit. The shoulder diameter is 8 mm with a tolerance of -0.025 to 0 mm, and the shoulder length is 10 mm with a tolerance of 0 to 0.05 mm, ensuring precise fit for alignment-critical assemblies. The product is manufactured to be RoHS 3 (2015/863/EU) compliant under exemption 6(c) for lead in copper alloy and is REACH (EC 1907/2006) compliant, adhering to stringent environmental and safety regulations.
