Professional Applications & Engineering Value
This M8 shoulder screw delivers exceptional engineering value in precision assembly applications where component alignment and rotational control are critical. The alloy steel construction with Rockwell B71 hardness provides the necessary strength to withstand operational stresses in machinery, automation systems, and precision equipment. The zinc plated finish offers reliable corrosion protection, making it suitable for industrial environments where moisture or chemical exposure may occur. The low profile socket head design combined with the precisely machined shoulder allows for secure mounting of bearings, pulleys, and other rotating components while maintaining minimal protrusion. The Class 6g thread fit ensures consistent engagement and reliable performance in vibration-prone applications, reducing maintenance requirements and improving equipment reliability.
Specification Summary & Compliance
This precision shoulder screw features M8x1.25 coarse metric threads with Class 6g thread fit tolerance for optimal engagement. The shoulder diameter maintains tight tolerance of -0.036mm to 0mm with shoulder length tolerance of 0.07mm to 0.15mm, ensuring precise component alignment. Manufactured to DIN 923 specifications for dimensional consistency and interchangeability. Fully compliant 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.
