- Precision Shoulder for Accurate Alignment – 16mm shoulder length with tight tolerance (±0.25mm) provides stable positioning for components.
- Secure Hex Drive Installation – 3mm hex socket drive allows for high-torque tightening without slippage.
- Knurled Head for Improved Grip – Easy handling and reduced risk of tool slip during manual or automated assembly.
- Wide Industrial Compliance – Meets ASTM A108 material standards and is RoHS 3/REACH compliant for global use.
- Coarse Thread for Quick Assembly – M5x0.8 coarse thread with Class 5g6g fit enables faster installation and secure fastening.
Professional Applications & Engineering Value
This M5 shoulder screw is engineered to address alignment and stability challenges in precision assemblies. The alloy steel construction, combined with a black oxide finish, offers superior resistance to corrosion and mechanical stress, making it ideal for robotics, machinery, and automotive applications. The 16mm shoulder length with controlled tolerances ensures exact component positioning, reducing vibration and misalignment. With a socket head and hex drive, installation is efficient and secure, supporting high-volume production lines. The coarse thread (M5x0.8) and Class 5g6g thread fit provide reliable engagement, minimizing the risk of loosening in dynamic environments.
Specification Summary & Compliance
This shoulder screw features a metric thread (M5x0.8) with Class 5g6g tolerance and a shoulder diameter tolerance of -0.072 to -0.01 mm. It complies with ASTM A108 material specifications and is RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, ensuring adherence to international safety and environmental standards.
