Key Features & Benefits at a Glance
- Enhanced Durability – Alloy steel construction with Rockwell C32 hardness ensures long-lasting performance in demanding applications.
- Superior Tensile Strength – Withstands up to 140,000 psi tensile and 84,000 psi shear forces for reliable load-bearing capacity.
- Precision Fit & Alignment – Class 5g6g thread fit and controlled shoulder diameter tolerance (-0.072 to -0.01 mm) guarantee accurate assembly and reduced play.
- Corrosion Resistance – Black oxide finish provides protection against rust and wear in harsh industrial environments.
- Efficient Installation – Hex socket drive (3 mm) allows for easy, secure tightening with standard tools, minimizing installation time.
- Versatile Shoulder Design – 15 mm shoulder length with standard fit acts as a precise spacer or pivot in mechanical assemblies.
- Global Compliance – Meets ISO 7379 standards and environmental regulations including RoHS 3 and REACH for safe, sustainable use.
Professional Applications & Engineering Value
This M5 shoulder screw is engineered to address critical alignment and load distribution challenges in precision machinery. The alloy steel core, combined with a black oxide finish, resists corrosion and mechanical stress, making it ideal for automotive, robotics, and industrial equipment where repeated motion and high forces are common. The 15 mm shoulder length provides a stable bearing surface, reducing wear on adjacent components and ensuring accurate positioning. With a coarse thread pitch and right-hand thread direction, it offers quick assembly and reliable holding power in metric-based systems, streamlining maintenance and improving overall system longevity.
Specification Summary & Compliance
This shoulder screw adheres to ISO 7379 manufacturing standards, with precise thread dimensions (M5x0.8, Class 5g6g fit) and shoulder tolerances (diameter: -0.072 to -0.01 mm; length: 0 to 0.25 mm). It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and suitability for global industrial markets.
