S-90269A241 M5 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh environments and chemical exposure
• Precise component alignment enabled by the smooth 18mm shoulder with controlled diameter tolerance for accurate positioning
• High mechanical reliability with 70,000 psi tensile strength and 35,000 psi shear strength for demanding applications
• Secure, tamper-resistant installation using the 3mm hex socket drive that prevents stripping and provides clean aesthetics
• Consistent thread engagement ensured by Class 5g6g thread fit and M5x0.8 coarse pitch for quick assembly and vibration resistance
• Extended service life due to Rockwell B79 hardness, maintaining dimensional stability under load
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global industrial use without hazardous substances

Professional Applications & Engineering Value

This M5 shoulder screw in 316 stainless steel addresses critical engineering challenges in precision machinery, automation systems, and marine equipment. The 18mm shoulder length acts as a precise spacer and pivot point, eliminating misalignment in assemblies while the hex socket drive allows flush mounting in confined spaces. Its corrosion-resistant properties prevent degradation in humid or chemical-laden environments, reducing maintenance frequency. The Class 5g6g thread fit ensures reliable fastening in vibrating applications, making it ideal for robotic arms, conveyor systems, and optical instruments where dimensional accuracy and high tensile strength are paramount.
