S-90269A564 M4 Shoulder Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance in harsh environments due to 316 Stainless Steel construction with Black Oxide finish
• Precise component alignment enabled by controlled shoulder diameter tolerance (-0.072 to -0.01 mm) for consistent assembly fit
• High-strength performance with 70,000 psi tensile strength and 35,000 psi shear strength for demanding mechanical applications
• Secure hex socket drive allows high torque application without stripping, maintaining fastener integrity
• Reliable thread engagement through Class 5g6g metric thread fit ensuring vibration-resistant connections
• Optimized shoulder-to-thread ratio with 25mm shoulder length and 10mm thread length for versatile spacing applications
• Full regulatory compliance with RoHS 3 and REACH standards for global industrial use

Professional Applications & Engineering Value

This M4 shoulder screw delivers critical engineering solutions where precise axial positioning and rotational stability are paramount. The 316 Stainless Steel base material combined with Black Oxide finish provides superior protection against chemical exposure and saltwater corrosion, making it ideal for marine equipment, food processing machinery, and chemical processing plants. The 25mm shoulder length acts as a precision spacer or pivot point in assemblies, eliminating the need for additional bushings while maintaining exact component alignment. The hex socket drive enables flush installation in confined spaces, while the Class 5g6g thread fit ensures consistent clamping force in vibrating environments. These precision shoulder bolts are engineered to replace multiple component assemblies, reducing inventory costs and simplifying maintenance in industrial automation, robotics, and precision machinery applications.

Specification Summary & Compliance

This metric shoulder screw features M4 x 0.7mm coarse threads with Class 5g6g thread fit per ISO standards, ensuring precise engagement. Shoulder diameter maintains -0.072 to -0.01 mm tolerance for controlled clearance fits, while shoulder length carries 0 to 0.25 mm tolerance for accurate spacing. Manufactured to Rockwell B79 hardness with 70,000 psi tensile strength mechanical properties. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for restricted substance control.
