• High mechanical strength and durability with a tensile strength of 70,000 psi and Rockwell B79 hardness, resisting wear and deformation.
• Secure, non-slip fastening enabled by the knurled socket head and 6mm hex drive, allowing for high-torque application.
• Reliable thread engagement and interchangeability with M10x1.5 coarse metric threads and Class 5g6g fit, ensuring compatibility and ease of assembly.
• Compliance with strict environmental regulations including RoHS 3 and REACH, making it suitable for global markets and sensitive applications.
• Versatile shoulder design providing a stable bearing surface for pivoting, locating, and spacing components in machinery.

Professional Applications & Engineering Value

This M10 shoulder screw is engineered to address critical challenges in precision assembly and motion control systems. The 316 stainless steel material offers exceptional resistance to corrosion and oxidation, making it perfect for applications in marine, chemical processing, and food-grade equipment where moisture and aggressive substances are present. The 80mm shoulder length acts as a precise axle or pivot point, reducing wear on mating parts and maintaining alignment in rotating assemblies like conveyor systems, robotic arms, and printing machinery. The knurled socket head with a 6mm hex drive ensures a firm grip, preventing tool slippage during installation and disassembly, which is crucial for maintenance in tight spaces. With its Class 5g6g thread fit and coarse thread pitch, it provides quick and secure fastening, minimizing the risk of cross-threading and enhancing productivity in high-volume manufacturing environments.

Specification Summary & Compliance
