Professional Applications & Engineering Value
This precision shoulder screw delivers exceptional engineering value in demanding industrial applications where component alignment and rotational stability are critical. The 18-8 stainless steel base material provides excellent corrosion resistance, while the TiCN coating significantly enhances surface hardness and reduces friction in high-wear environments. The hex socket drive ensures maximum torque transmission without cam-out, making it ideal for automated assembly processes. With its precise shoulder diameter and controlled tolerances, this metric shoulder screw maintains accurate component positioning in machinery, robotics, and precision equipment, solving alignment challenges while providing reliable, long-lasting performance in heavy-duty applications.
Specification Summary & Compliance
This M5 x 0.8mm shoulder screw features Class 6g thread tolerance with coarse thread spacing, ensuring compatibility with standard metric components. The shoulder diameter maintains -0.025 to 0 mm tolerance while the shoulder length is controlled within 0 to 0.05 mm for precise fitment. Manufactured to Rockwell B55 hardness and 70,000 psi tensile strength specifications, this fastener complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for global industrial applications requiring strict material compliance standards.
