Key Features & Benefits at a Glance
- Enhanced Durability – Alloy steel construction with Rockwell C32 hardness ensures long-lasting performance in demanding industrial environments.
- Superior Tensile Strength – 140,000 psi tensile strength and 84,000 psi minimum shear strength provide reliable load-bearing capacity for critical assemblies.
- Precision Shoulder Fit – 20mm shoulder length with tight diameter tolerance (-0.072 to -0.01mm) enables accurate component alignment and reduced wear.
- Secure Hex Drive – 3mm hex socket drive with knurled head prevents tool slippage and allows for high-torque installation.
- Corrosion-Resistant Finish – Black oxide coating offers improved resistance to rust and oxidation in various operating conditions.
- Standardized Thread Design – M5x0.8 coarse pitch with Class 5g6g thread fit ensures compatibility and easy assembly with metric components.
- Environmental Compliance – Meets RoHS 3 and REACH regulations, making it suitable for use in regulated industries and global markets.
Professional Applications & Engineering Value
This M5 shoulder screw is engineered to address alignment and wear challenges in precision assemblies. The alloy steel material and black oxide finish provide exceptional strength and moderate corrosion resistance, ideal for machinery, automotive, and automation systems where repeated adjustments are common. The 20mm shoulder length acts as a precise pivot or spacer, reducing friction and maintaining component positioning under vibration or load. With a coarse thread pitch and Class 5g6g thread fit, it ensures quick installation and reliable holding power in industrial fasteners applications, minimizing downtime and maintenance costs.
Specification Summary & Compliance
This shoulder screw features a metric M5x0.8 coarse thread with Class 5g6g tolerance, a shoulder diameter of 6mm (-0.072 to -0.01mm tolerance), and shoulder length of 20mm (0 to 0.25mm tolerance). It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and suitability for international engineering standards.
