Professional Applications & Engineering Value
This M8 shoulder screw is engineered to solve critical alignment and pivot-point challenges in industrial machinery. The 316 stainless steel material provides exceptional resistance to chemicals and corrosion, making it perfect for food processing, marine, and pharmaceutical equipment. The long, 90mm shoulder length acts as a precise shaft for gears, bearings, and linkages, eliminating the need for separate spacers and reducing assembly complexity. The M8x1.25 coarse thread and hex socket drive allow for high clamp force and easy access in confined spaces. This design directly addresses the need for durable, precision components that maintain integrity under load and in corrosive environments, streamlining your design and reducing long-term maintenance.
Specification Summary & Compliance
This metric shoulder screw features an M8x1.25 thread with a Class 5g6g thread fit and a shoulder diameter tolerance of -0.072 to -0.01 mm for high precision. It is manufactured in compliance with ISO 7379 and meets the requirements of RoHS 3 (2015/863/EU) and REACH (EC 1907/2006).
