S-90323A487 M8 Shoulder Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 18-8 stainless steel and passivated finish, ideal for harsh industrial environments
• Superior strength and durability with 80,000 psi tensile strength and Rockwell B95 hardness for high-stress applications
• Precise component alignment thanks to the 10mm shoulder diameter with tight tolerances (-0.025 to 0 mm)
• Secure, low-profile installation using a 5mm hex drive, minimizing protrusion in compact assemblies
• Reliable thread engagement with Class 6g metric coarse thread (M8x1.25) ensuring consistent fastening performance
• Compliance with environmental standards including RoHS 3 and REACH, meeting global regulatory requirements
• Optimized for repetitive use with a smooth, low-profile socket head that withstands frequent adjustments

Professional Applications & Engineering Value

This M8 shoulder screw is engineered to address critical alignment and wear challenges in precision machinery. The 18-8 stainless steel construction, enhanced by a passivated finish, provides excellent resistance to corrosion and oxidation, extending service life in demanding conditions like automation systems and assembly fixtures. The precise shoulder diameter (10mm) and length (14mm) with minimal tolerances ensure accurate positioning of moving parts, reducing vibration and misalignment. The low-profile socket head with a 5mm hex drive allows for easy installation in confined spaces, while the Class 6g coarse thread (M8x1.25) offers quick assembly and high load distribution. Ideal for use in robotics, conveyor systems, and tooling jigs, this screw enhances operational reliability and reduces maintenance downtime.
