• Durable Steel Construction – Made from hardened steel with Rockwell C20 hardness, it offers excellent resistance to wear and deformation, extending service life in repetitive-use machinery.
• Easy Installation and Removal – The external hex drive and smooth hex head allow for quick, secure tightening with standard tools, speeding up assembly and maintenance processes.
• Reliable Thread Engagement – Class 6g thread fit and coarse 1.75 mm pitch provide secure fastening with reduced cross-threading risk, ensuring consistent performance in high-vibration settings.
• Compliance with International Standards – Meets DIN 609 specifications, guaranteeing dimensional accuracy and interchangeability in metric-based engineering projects.
• Environmentally Safe Manufacturing – RoHS 3 and REACH compliance ensures the screw is free from hazardous substances, supporting sustainable and safe industrial operations.

Professional Applications & Engineering Value

This M12 shoulder screw is engineered to address critical alignment and durability challenges in precision assemblies. The steel construction and Rockwell C20 hardness provide robust resistance against shear forces and wear, making it ideal for machinery, automation systems, and fixture jigs where repeated adjustments are common. The 13 mm shoulder diameter with minimal tolerance acts as a precise pivot or spacer, eliminating misalignment in rotating parts or guiding components. Combined with a Class 6g thread fit and coarse pitch, it ensures quick assembly and reliable holding power even under dynamic loads. Industries such as automotive manufacturing, industrial robotics, and precision equipment rely on these metric shoulder screws for their consistent performance and compliance with DIN 609 standards, streamlining production and reducing downtime.
