S-97713A126 M12 DIN 609 Shoulder Screws

Key Features & Benefits at a Glance

• Enhanced load distribution with precise 13mm shoulder diameter and tight 0.001-0.012mm tolerance for stable component alignment
• Superior mechanical strength from Rockwell C20 hardened steel construction, supporting up to 120,000 psi tensile stress in demanding applications
• Quick assembly efficiency with coarse 1.75mm pitch threads and Class 6g fit, reducing installation time while maintaining secure fastening
• Reliable torque transmission through 19mm external hex head design, preventing tool slippage during high-torque applications
• Long-term corrosion resistance with smooth steel surface finish, ensuring consistent performance in industrial environments
• Regulatory compliance assurance meeting DIN 609 standards plus RoHS 3 and REACH environmental directives for global market acceptance
• Precision dimensional control with 74.5mm shoulder length (-1 to 0mm tolerance) enabling accurate spacing in machinery and fixtures

Professional Applications & Engineering Value

Engineered for precision mechanical assemblies, these M12 shoulder screws solve critical alignment challenges in industrial equipment. The 13mm shoulder diameter with micron-level tolerance provides exact locating surfaces for bearings, gears, and rotating components, eliminating play in high-vibration environments. Manufactured from hardened steel with Rockwell C20 hardness, they maintain dimensional stability under continuous 120,000 psi tensile loads. The coarse metric thread (1.75mm pitch) with Class 6g fit ensures rapid installation in production lines while the 22.5mm thread length delivers sufficient engagement in tapped holes. Ideal for automation systems, printing machinery, and precision fixtures where shoulder length accuracy directly impacts operational reliability.

Specification Summary & Compliance
