• Easy installation and removal using the 3mm hex socket drive, providing secure torque transmission without stripping
• Accurate thread engagement with Class 6g metric coarse thread (M5x0.8) for consistent fastening in right-hand applications
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe use in global markets
• Optimized for automated assembly featuring smooth head texture and standard socket profile for efficient handling

Professional Applications & Engineering Value

Engineered for precision motion control and pivot applications, these M5 shoulder screws solve critical alignment challenges in machinery and electronic assemblies. The 360 Brass material offers excellent machinability and natural lubricity, reducing galling in high-cycle operations while maintaining corrosion resistance. The precise shoulder diameter with tight tolerances acts as a reliable locating feature for bearings, gears, and linkages, eliminating the need for additional bushings. With 10mm thread length and Class 6g coarse threads, installation is streamlined in industrial equipment, automotive components, and precision instruments where vibration resistance and repeatable positioning are paramount. The socket head hex drive ensures secure fastening in confined spaces common in B2B manufacturing environments.
