Key Features & Benefits at a Glance
- Exceptional durability and corrosion resistance with black oxide finish, ideal for harsh industrial environments
- Precise component alignment and reduced wear thanks to the 6mm shoulder with tight diameter tolerance of -0.072 to -0.01 mm
- High load-bearing capacity and reliability from alloy steel construction with 140,000 psi tensile strength and Rockwell C32 hardness
- Secure, non-slip installation enabled by the knurled socket head and 3 mm hex drive
- Wide compatibility and easy assembly with standard M5x0.8 mm coarse right-hand thread and Class 5g6g fit
- Consistent performance in regulated industries by meeting ASTM A108, RoHS 3, and REACH compliance standards
- Reduced risk of thread damage and stripping due to the coarse thread spacing, ensuring robust fastening
Professional Applications & Engineering Value
This M5 shoulder screw is engineered to address critical alignment and strength requirements in precision assemblies. The alloy steel material, combined with a black oxide finish, provides superior resistance to wear and environmental factors, making it suitable for automotive, machinery, and electronics applications. The 6mm shoulder length with minimal tolerances ensures accurate positioning of moving parts, reducing vibration and misalignment issues. The socket head with hex drive allows for high-torque installation in confined spaces, while the coarse metric thread (M5x0.8mm) facilitates quick assembly and disassembly. Ideal for use in jigs, fixtures, and rotating mechanisms, this screw enhances operational efficiency and extends equipment lifespan by maintaining structural integrity under high-stress conditions.
Specification Summary & Compliance
This shoulder screw features a Class 5g6g thread fit and precise shoulder diameter tolerance of -0.072 to -0.01 mm, ensuring reliable performance in metric-based systems. It is manufactured in accordance with ASTM A108 specifications and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing safety and environmental standards for global industrial use.
