S-96654A117 M3 Shoulder Screws

Key Features & Benefits at a Glance

• Secure Vibration Resistance: Permanent nylon patch thread locking prevents loosening under dynamic loads, maintaining assembly integrity in high-vibration environments.
• Superior Corrosion Resistance: 18-8 stainless steel construction with passivated finish provides excellent protection against rust and chemical exposure, ensuring long-term durability.
• Precision Alignment & Bearing Surface: 14mm shoulder length with tight tolerances offers a precise pivot point or spacer, reducing wear on connected components.
• High Strength & Durability: Rockwell B55 hardness and 70,000 psi tensile strength deliver reliable performance under heavy mechanical stress.
• Wide Temperature Compatibility: Nylon patch functions effectively from -70° to 250°F, suitable for diverse industrial operating conditions.
• Accurate Thread Engagement: Class 6g thread fit ensures consistent, secure fastening with standard M3 x 0.5mm coarse threaded components.
• Easy Installation & Maintenance: Hex socket drive (2mm) allows for straightforward tool access and torque application in confined spaces.

Professional Applications & Engineering Value

This precision shoulder screw is engineered to address critical alignment and retention challenges in industrial applications. The 14mm shoulder length with minimal tolerance provides a stable bearing surface, preventing axial movement and reducing wear in machinery assemblies, robotics, and precision instruments. Made from 18-8 stainless steel with a passivated finish, it resists corrosion in harsh environments, while the integrated nylon patch locking feature eliminates the need for separate lock washers or adhesives, streamlining assembly and enhancing reliability. The Class 6g thread fit and hex drive design ensure quick, secure installation, making it ideal for high-stress applications where vibration resistance and dimensional accuracy are paramount.

Specification Summary & Compliance

This M3 x 0.5mm shoulder screw features a Class 6g thread fit per metric standards, with shoulder diameter tolerance of -0.025 to 0 mm and shoulder length tolerance of 0 to 0.05 mm for precise assembly. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and suitability for global industrial use.
