S-96654A116 M3 Shoulder Screws

Key Features & Benefits at a Glance

• Vibration-resistant performance with built-in nylon patch thread locker that maintains secure fastening from -70° to 250°F
• Exceptional corrosion resistance thanks to 18-8 stainless steel construction and passivated finish for harsh industrial environments
• Precise alignment and stability achieved through controlled shoulder diameter tolerance (-0.025 to 0mm) and 12mm shoulder length
• Reliable mechanical strength with Rockwell B55 hardness and 70,000 psi tensile strength for heavy-duty applications
• Secure hex drive engagement via 2mm socket head design preventing tool slippage during installation
• Industry-standard compatibility with Class 6g thread fit ensuring consistent performance in metric assemblies
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global industrial use

Professional Applications & Engineering Value

This precision shoulder screw solves critical alignment challenges in industrial machinery, automation systems, and precision instruments. The M3 metric thread with 0.5mm coarse pitch combined with the precisely machined shoulder creates a dual-function fastener that both secures components and maintains exact positioning. The nylon patch locking technology prevents loosening under vibration, eliminating the need for separate locking washers in applications ranging from robotic arms to conveyor systems. Manufactured from 18-8 stainless steel with passivated finish, it withstands corrosive environments while the socket head design allows for high-torque installation in confined spaces. These engineering features make it ideal for OEM applications requiring repeated disassembly and reassembly without performance degradation.

Specification Summary & Compliance

This M3 shoulder screw features Class 6g thread fit per metric standards with precise shoulder diameter tolerance (-0.025 to 0mm) and shoulder length tolerance (0 to 0.05mm). The fastener meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements, ensuring environmental regulation adherence for industrial applications worldwide. Manufacturing follows standardized metric thread specifications with right-hand threading and coarse pitch spacing for optimal performance in demanding mechanical assemblies.
