• Secure, Non-Slip Fastening – Knurled socket head with 3 mm hex drive prevents tool slippage and allows for consistent torque application.
• Accurate Thread Engagement – Class 5g6g thread fit and M5x0.8 coarse thread design enable quick, reliable installation with reduced cross-threading risk.
• Broad Industrial Compliance – Meets RoHS 3 and REACH standards, ensuring environmental and safety compatibility for global supply chains.
• Versatile Metric Sizing – M5 thread with 10mm length and standard right-hand threading suits a wide range of metric-based machinery and equipment.

Professional Applications & Engineering Value

This M5 shoulder screw is engineered to address critical alignment and durability challenges in precision assemblies. The alloy steel core, hardened to Rockwell C32, ensures high tensile strength (140,000 psi) and resistance to dynamic loads, making it ideal for rotating components, pivoting mechanisms, and industrial machinery. The black oxide finish enhances corrosion resistance, while the precisely machined 40mm shoulder with minimal tolerance variation provides a stable bearing surface that reduces wear on mating parts. With its Class 5g6g thread fit and coarse M5x0.8 thread, this screw offers quick, secure fastening in applications such as automation systems, motor mounts, and jigs—where repeatable accuracy and shear strength (84,000 psi) are paramount.

Specification Summary & Compliance
