S-96654A141 M5 Shoulder Screws

Key Features & Benefits at a Glance

• Vibration-resistant locking with permanent nylon patch thread locker that maintains secure fastening in temperatures from -70° to 250°F
• Superior corrosion resistance thanks to 18-8 stainless steel construction and passivated finish for extended service life in harsh environments
• Precise component alignment with Class 6g thread fit and controlled shoulder diameter tolerance (-0.025 to 0mm) for accurate positioning
• High strength reliability with 70,000 psi tensile strength and Rockwell B55 hardness for demanding industrial applications
• Easy installation and removal with standard hex socket drive (3mm) and smooth head texture for efficient maintenance
• Consistent dimensional accuracy with tight shoulder length tolerance (0 to 0.05mm) ensuring repeatable assembly performance
• Environmental compliance meeting RoHS 3 and REACH regulations for safe use across global markets

Professional Applications & Engineering Value

This M5 shoulder screw delivers exceptional engineering value in applications requiring precise axial positioning and vibration resistance. The 12mm shoulder length with tight tolerances provides accurate component spacing in assemblies, while the nylon patch thread locker eliminates the need for separate locking hardware in rotating equipment, machinery, and automotive subsystems. Manufactured from 18-8 stainless steel with passivated finish, it withstands corrosive environments where carbon steel fasteners would fail. The combination of Class 6g thread fit and controlled shoulder dimensions ensures reliable performance in precision instruments, manufacturing jigs, and robotic systems where dimensional stability is critical.

Specification Summary & Compliance
