S-90323A471 M5 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel and passivated finish for long-lasting performance in harsh environments
• Precise component alignment thanks to the 6mm shoulder diameter with tight tolerance (-0.025 to 0mm) for accurate positioning
• High-strength durability with 80,000 psi tensile strength and Rockwell B95 hardness to withstand heavy loads and vibrations
• Secure, low-profile installation using the hex socket drive and smooth low-profile head for flush mounting in confined spaces
• Reliable thread engagement with Class 6g metric coarse thread (M5x0.8) ensuring consistent fastening in industrial assemblies
• Environmental compliance meeting RoHS 3 and REACH standards for safe use in regulated industries
• Optimized shoulder length at 45mm with minimal tolerance (+0.05mm) for exact spacing in precision machinery

Professional Applications & Engineering Value

This precision shoulder screw is engineered to solve critical alignment and durability challenges in industrial equipment. The 18-8 stainless steel construction with passivated finish provides excellent corrosion resistance, making it ideal for machinery exposed to moisture, chemicals, or outdoor conditions. The 45mm shoulder length with tight tolerance ensures precise component spacing in assemblies like rotating shafts, gears, and bearings, eliminating misalignment issues. The hex socket drive allows for high-torque installation without slippage, while the Class 6g thread fit on the M5x0.8 coarse thread guarantees secure fastening in vibrating environments. These features make it invaluable for industrial automation, precision machinery, and automotive applications where reliability and exact tolerances are paramount.
