S-90323A217 M3 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction and passivated finish for long-lasting performance in harsh environments
• Precise component alignment ensured by the accurate 16mm shoulder with tight diameter and length tolerances for reliable assembly
• High-strength durability with Rockwell B95 hardness and 80,000 psi tensile strength to withstand demanding industrial loads
• Secure, low-profile installation using the 2mm hex socket drive that minimizes head protrusion while providing excellent torque transfer
• Consistent thread engagement with Class 6g metric coarse threads (M3x0.5) for reliable fastening in right-hand applications
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe use across regulated industries
• Space-saving design with low socket head profile ideal for compact assemblies where clearance is limited

Professional Applications & Engineering Value

This precision shoulder screw delivers exceptional engineering value in applications requiring exact component positioning and rotational control. The 18-8 stainless steel material with passivated finish provides excellent corrosion resistance, making it ideal for machinery, automation systems, and electronic enclosures exposed to moisture or chemicals. The precisely machined 16mm shoulder with tight diameter tolerance acts as a reliable pivot point or spacer, eliminating the need for additional components in assemblies. The hex socket drive with low profile head allows for secure installation in confined spaces while maintaining structural integrity under the 80,000 psi tensile strength. These metric shoulder screws are particularly valuable in precision equipment, robotics, and manufacturing jigs where repeatable alignment and durability are critical.
