- Precise alignment and smooth rotation due to the 20mm shoulder length and controlled diameter tolerance, reducing wear in assemblies.
- Corrosion-resistant black oxide finish extends service life by protecting against rust in demanding industrial environments.
- Secure, slip-resistant installation with a knurled socket head and 5mm hex drive, allowing for consistent torque application.
- Accurate thread engagement with Class 5g6g fit and coarse M8x1.25 thread, facilitating quick assembly and vibration resistance.
- Compliance with environmental standards including RoHS 3 and REACH, ensuring safe use in regulated industries.
- Versatile metric design with right-hand threading for broad compatibility in machinery and equipment.
Professional Applications & Engineering Value
This M8 shoulder screw is engineered to address common industrial challenges such as misalignment and component wear. The alloy steel construction, combined with a black oxide finish, provides superior strength and corrosion resistance, making it ideal for precision mechanisms in automation, automotive, and machinery. The 20mm shoulder length acts as a precise pivot or spacer, reducing friction and maintaining alignment in rotating assemblies. With a knurled socket head and 5mm hex drive, it ensures secure fastening even in tight spaces, while the Class 5g6g thread fit guarantees consistent performance in high-tensile applications.
Specification Summary & Compliance
This shoulder screw features a metric M8x1.25 coarse thread with Class 5g6g thread fit for precise tolerance. Dimensions include a shoulder diameter of 10 mm (tolerance: -0.072 to -0.01 mm) and shoulder length of 20 mm (tolerance: 0 to 0.25 mm). It complies with RoHS 3 (2015/863/EU) under exemption 6(a) and REACH (EC 1907/2006), ensuring adherence to environmental and safety regulations for industrial components.
