Professional Applications & Engineering Value

This M10 shoulder screw is engineered to address critical alignment and durability challenges in industrial machinery. The 18-8 stainless steel material provides excellent resistance to rust and chemical exposure, making it suitable for food processing, marine, and outdoor equipment. The hex socket head with knurling allows for secure tool engagement in tight spaces, reducing installation time and preventing damage. With a Class 5g6g thread fit and coarse 1.5 mm pitch, it ensures quick assembly and high vibration resistance, ideal for securing bearings, pulleys, and linkages in automated systems. The precision shoulder diameter acts as a pivot or axle, maintaining exact part alignment and reducing wear on moving components, thereby lowering maintenance costs and improving operational reliability.

Specification Summary & Compliance

This shoulder screw adheres to metric system standards with an M10 thread size and 1.5 mm coarse pitch. Threads are manufactured to Class 5g6g tolerance for consistent fit. Shoulder dimensions include a diameter of 12 mm with tight tolerances (e.g., -0.072 to -0.01 mm) and length options from 6 to 49.75 mm. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for international engineering projects.
