S-97713A102 M8 DIN 609 Shoulder Screws

Key Features & Benefits at a Glance

• Enhanced alignment precision with ±0.001-0.01mm shoulder diameter tolerance for consistent component positioning
• Superior load-bearing capacity from 120,000 psi tensile strength steel construction
• Optimized assembly efficiency through coarse 1.25mm pitch threading and external hex drive design
• Reliable thread engagement ensured by Class 6g thread fit meeting international metric standards
• Long-term operational durability with Rockwell C20 hardness and smooth head surface
• Regulatory compliance assurance through DIN 609 certification and RoHS 3/REACH environmental standards
• Versatile industrial compatibility with right-hand thread direction and 13mm shoulder length

Professional Applications & Engineering Value

This M8 shoulder screw delivers critical precision in automated machinery, robotics, and precision instrument assemblies where component alignment directly impacts operational accuracy. The steel construction with Class 6g thread fit prevents backlash in rotating assemblies while the 13mm shoulder length provides stable bearing surfaces for gears, pulleys, and linkages. Engineers specify this DIN 609 certified fastener for applications requiring consistent axial positioning under dynamic loads, with the external hex drive enabling high-torque installation in confined spaces. The combination of coarse metric threading and precise shoulder dimensions solves vibration-induced loosening challenges in industrial equipment.
