S-97713A118 M12 DIN 609 Shoulder Screws

Key Features & Benefits at a Glance

• High tensile strength of 120,000 psi ensures reliable performance in demanding mechanical assemblies and reduces the risk of fastener failure.
• Precision Class 6g thread fit guarantees consistent engagement and secure fastening, minimizing assembly play and vibration loosening.
• Hardened steel construction (Rockwell C20) provides excellent wear resistance and durability for long service life in high-stress applications.
• 16.5mm shoulder length with minimal tolerance offers precise component location and alignment, simplifying assembly and improving overall product accuracy.
• 13mm shoulder diameter with tight tolerance control (±0.001mm) ensures a perfect fit for bearings and pulleys, reducing wear and maintenance needs.
• External hex head design allows for high-torque installation with standard tools, speeding up assembly and disassembly processes.
• Compliance with DIN 609, RoHS 3, and REACH assures material quality and environmental safety for use in regulated industries and global markets.

Professional Applications & Engineering Value

This M12 shoulder screw is engineered to solve critical alignment and positioning challenges in precision industrial applications. The steel construction, hardened to Rockwell C20, provides the necessary strength to withstand rotational forces and shock loads in machinery. The integrated shoulder with its exceptionally tight diameter tolerance acts as a precise pivot or axle, eliminating the need for separate spacers or bushings in assemblies involving gears, linkages, or bearings. The coarse metric thread (1.75mm pitch) with a Class 6g fit ensures rapid and secure installation, reducing assembly time while providing vibration resistance. This makes the screw ideal for automation equipment, conveyor systems, and other high-precision mechanisms where reliability and repeatability are paramount.

Specification Summary & Compliance

This precision shoulder screw conforms to DIN 609 specifications. The metric thread is M12 x 1.75mm with a Class 6g tolerance for general-purpose use. The shoulder features a diameter of 13 mm with a tolerance from 0.001 to 0.012 mm and a length of 16.5 mm with a tolerance of -1 to 0 mm. The component is manufactured from steel and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
