S-90323A252 M8 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction and passivated finish, ideal for harsh industrial environments
• Exceptional mechanical strength with 80,000 psi tensile strength and Rockwell B95 hardness for reliable performance under heavy loads
• Precision alignment and positioning enabled by the 10mm shoulder diameter with tight ±0.05mm length tolerance
• Easy installation in confined spaces thanks to the low-profile socket head design with 5mm hex drive
• Consistent thread engagement ensured by Class 6g thread fit and M8x1.25 coarse thread specification
• Environmental compliance assurance meeting RoHS 3 and REACH regulations for global manufacturing applications
• Reduced assembly time through standardized metric threading and right-hand thread direction

Professional Applications & Engineering Value

This M8 shoulder screw delivers critical engineering value in precision assembly applications where component alignment and rotational stability are paramount. The 18-8 stainless steel construction with passivated finish provides exceptional corrosion resistance, making these socket head shoulder bolts ideal for machinery, automation systems, and electronic enclosures exposed to moisture or chemicals. The precisely machined 10mm shoulder diameter with tight tolerances ensures accurate bearing surfaces and shaft positioning, eliminating play in rotating assemblies. The low-profile socket head design allows installation in space-constrained applications while maintaining high torque capability. These precision shoulder screws solve common engineering challenges including misalignment, component wear, and corrosion-induced failure in demanding industrial environments.
