Professional Applications & Engineering Value
This M8 shoulder screw is engineered to solve critical alignment and pivot point challenges in precision machinery, automation systems, and industrial equipment. The 316 Stainless Steel material provides excellent resistance to chemicals, saltwater, and oxidizing agents, making it suitable for marine, chemical processing, and food-grade applications. The integral 50mm shoulder acts as a precise locating dowel or axle, eliminating the need for additional bushings and reducing assembly parts. The knurled socket head ensures a non-slip grip during installation, even with lubricated gloves, while the coarse thread (M8x1.25mm) allows for rapid installation and maintains a secure hold in materials where fine threads might strip. This combination of corrosion resistance, high strength, and precision delivers long-term reliability and reduces maintenance downtime.
Specification Summary & Compliance
This shoulder screw features an M8x1.25mm coarse metric thread with a Class 5g6g thread fit for standard clearance. The shoulder diameter is 10 mm with a tolerance of -0.072 to -0.01 mm, and the shoulder length is 50 mm with a tolerance of 0 to +0.25 mm, ensuring precise dimensional control. The product is manufactured in accordance with ISO 7379 and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
