Professional Applications & Engineering Value
This M8 shoulder screw delivers exceptional engineering value in precision assembly applications where component alignment and rotational clearance are critical. The alloy steel construction with zinc plating provides both the mechanical strength and corrosion protection needed for industrial machinery, automotive components, and manufacturing equipment. The precisely machined shoulder diameter of 10 mm with tight tolerance control ensures perfect bearing surfaces and eliminates the need for additional spacing components. The low-profile socket head design allows for compact installations while maintaining high torque transmission capability. These metric shoulder screws solve common alignment issues in rotating assemblies, reducing wear and maintenance requirements while improving overall system reliability.
Specification Summary & Compliance
This precision fastener features Class 6g thread fit with M8x1.25 coarse pitch threading, ensuring reliable engagement and consistent performance. The shoulder diameter maintains a tight tolerance of -0.036 mm to 0 mm, while the shoulder length is controlled within 0.1 mm to 0.2 mm tolerance. Manufactured to DIN 923 specifications, these screws comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, making them suitable for global industrial applications requiring certified components.
