• Precise and secure engagement with a Class 6g thread fit, ensuring consistent assembly quality and vibration resistance.
• Easy installation and removal using a standard 3 mm hex key, providing a secure, non-slip drive for efficient maintenance.
• Full thread coverage along the entire 16 mm length for maximum grip and uniform stress distribution in assemblies.
• Compliance with strict environmental regulations including RoHS 3 and REACH, making them safe for use in regulated industries.

Professional Applications & Engineering Value

Engineered for demanding industrial applications, these M5 socket head cap screws in 316 Stainless Steel provide a robust solution where corrosion and high strength are critical. The ultra-low socket head profile minimizes protrusion, making them perfect for compact machinery, precision instruments, and automotive assemblies where space optimization is essential. With a coarse thread (M5 x 0.8mm) and Class 6g thread fit, they offer quick assembly and reliable performance in high-vibration environments, reducing the risk of loosening. The 3 mm hex drive ensures easy torque application, enhancing installation efficiency in automated or manual processes. Ideal for use in chemical processing, marine equipment, and food-grade machinery, these screws deliver long-term durability and consistent performance under stress.

Specification Summary & Compliance

This metric socket head screw adheres to precise dimensional standards, including a Class 6g thread tolerance for accurate fit. The manufacturing specifications ensure consistent head diameter (8.5 mm) and length (16 mm), supporting reliable assembly. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its safety for environmental and health standards in industrial use.
