S-98451A126 M5 Shoulder Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance from 360 brass construction, ideal for harsh industrial environments
• Precise component alignment with controlled 6mm shoulder diameter and tight tolerances (-0.025 to 0mm)
• Superior torque transmission through hex socket drive design, preventing stripping during installation
• Reliable thread engagement with Class 6g metric coarse threads ensuring consistent fastening performance
• Optimized mechanical strength with Rockwell B55 hardness and 40,000 psi tensile strength
• Simplified regulatory compliance meeting RoHS 3 and REACH standards for global industrial applications
• Reduced assembly time with right-hand coarse threads enabling quick installation and adjustment

Professional Applications & Engineering Value

This precision shoulder screw addresses critical alignment challenges in mechanical assemblies where component positioning accuracy is paramount. The 360 brass material provides excellent corrosion resistance while maintaining the Rockwell B55 hardness required for durable performance in rotating machinery, precision instruments, and automated equipment. The 6mm shoulder diameter with precise tolerances ensures perfect bearing surfaces and pivot points, eliminating misalignment issues that can cause premature wear. The M5x0.8 coarse thread with Class 6g fit offers reliable fastening in metric applications, while the socket head hex drive allows for high-torque installation in confined spaces. This combination makes it ideal for industrial applications requiring both precision alignment and corrosion resistance.

Specification Summary & Compliance

This metric shoulder screw features M5x0.8 coarse threads with Class 6g thread fit per ISO standards, ensuring proper engagement in industrial assemblies. The precision shoulder maintains tight diameter tolerance of -0.025 to 0mm and length tolerance of 0 to 0.05mm for accurate component alignment. Manufactured from 360 brass with Rockwell B55 hardness and 40,000 psi tensile strength, the screw complies with RoHS 3 (2015/863/EU) with exemption 6(c) for lead in copper alloy and REACH (EC 1907/2006) regulations, meeting international environmental standards for industrial components.
