Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments.
- Precise component alignment ensured by the 25mm shoulder with tight diameter tolerance (-0.04 to -0.01mm).
- High mechanical strength providing 70,000 psi tensile and 35,000 psi shear strength for reliable, heavy-duty applications.
- Enhanced durability from Rockwell B55 hardness and a protective black oxide finish that resists wear.
- Secure, non-slip installation with a knurled head and hex socket drive for firm tool grip.
- Broad compatibility with Class 5g6g coarse threads (M5x0.8) for easy assembly in metric systems.
- Compliance with environmental regulations including RoHS 3 and REACH, ensuring safe use in regulated industries.
Professional Applications & Engineering Value
This M5x0.8 metric shoulder screw is engineered to solve critical alignment and pivot point challenges in machinery and assemblies. The 25mm shoulder length with minimal diameter tolerance acts as a precise locating dowel, reducing part misalignment and wear in rotating components like gears, pulleys, and linkages. Made from 18-8 stainless steel and finished with black oxide, it offers excellent corrosion resistance in demanding environments such as automotive, packaging, and automation equipment. The coarse thread and Class 5g6g fit ensure quick, secure fastening, while the knurled head and hex socket drive prevent tool slippage during installation, enhancing assembly efficiency and reliability in industrial shoulder bolt applications.
Specification Summary & Compliance
This precision shoulder screw adheres to metric system standards with an M5x0.8 coarse thread in Class 5g6g tolerance. The shoulder diameter is tightly controlled at -0.04 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm for consistent performance. It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free of hazardous substances for safe industrial and commercial use.
