Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments.
- Enhanced durability and wear resistance from the black oxide finish, reducing maintenance needs.
- High tensile and shear strength (70,000 psi tensile, 45,000 psi shear) ensures reliable performance under heavy loads.
- Precise alignment and smooth rotation due to the accurately machined shoulder with tight diameter tolerance.
- Secure, non-slip installation with a knurled head and 6 mm hex drive for easy torque application.
- Wide compatibility with coarse M8x1.25mm metric threads (Class 5g6g fit) for standard assemblies.
- Compliance with international standards including ISO 7379, RoHS 3, and REACH for quality and safety assurance.
Professional Applications & Engineering Value
This M8 shoulder screw is engineered to address common challenges in precision machinery, such as misalignment and component wear. The 18-8 stainless steel material offers excellent resistance to rust and corrosion, making it suitable for applications in automotive, aerospace, and manufacturing equipment. The black oxide finish not only enhances aesthetics but also provides an extra layer of protection against abrasion. With a knurled head and hex drive, it ensures firm gripping during assembly, reducing the risk of tool slippage. The precisely toleranced shoulder diameter and length allow for accurate positioning of moving parts, minimizing vibration and extending service life in high-stress environments like conveyor systems or robotic arms.
Specification Summary & Compliance
This shoulder screw features an M8x1.25mm coarse metric thread with a Class 5g6g fit for standard assembly tolerances. The shoulder diameter is 12 mm with a tolerance of -0.072 to -0.01 mm, and the shoulder length is 14 mm with a tolerance of 0 to 0.25 mm, ensuring precise engineering alignment. It complies with ISO 7379 manufacturing standards and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations for environmental safety and material restrictions.
