- Precise alignment and smooth rotation enabled by the 170mm shoulder with a tightly controlled diameter tolerance.
- Secure and non-slip installation with a knurled head and 10mm hex socket drive for reliable torque transfer.
- Guaranteed dimensional consistency and interchangeability, manufactured to meet the stringent ISO 7379 standard.
- Enhanced durability and wear resistance from the black oxide finish and Rockwell B79 hardness rating.
- Compliance with global environmental regulations including RoHS 3 and REACH, ensuring safe and responsible use.
Professional Applications & Engineering Value
This M16x2mm shoulder screw is engineered to solve critical alignment and pivot point challenges in precision industrial applications. The 316 stainless steel material provides excellent resistance to chemicals and saltwater corrosion, making it suitable for marine, chemical processing, and food machinery. The long, 170mm shoulder length acts as a precise shaft for rotating components like gears, pulleys, and linkages, eliminating the need for separate bushings and reducing assembly complexity. The black oxide finish not only adds a layer of corrosion protection but also reduces galling. Combined with the Class 5g6g thread fit and coarse thread pitch, it ensures reliable fastening in high-vibration environments, providing long-term reliability and reducing maintenance downtime.
Specification Summary & Compliance
This shoulder screw features a metric M16x2mm coarse thread with a Class 5g6g thread fit and a right-hand thread direction. The shoulder diameter is 20 mm with a tolerance of -0.072 to -0.01 mm, and the shoulder length is 170 mm with a tolerance of 0 to 0.25 mm. It is manufactured in compliance with ISO 7379 and conforms to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
