• High mechanical strength offering 70,000 psi tensile and 35,000 psi shear strength for reliable load-bearing applications.
• Precise Class 3A thread fit ensures tight, secure fastening with minimal backlash in assemblies.
• Enhanced installation control via hex socket drive and knurled head texture for non-slip tool engagement.
• Durable shoulder design provides accurate component alignment and spacing with controlled diameter and length tolerances.
• Compliance with global regulations including RoHS 3 and REACH, ensuring safe use in regulated industries.
• Coarse UNC threads enable quick assembly and disassembly, reducing installation time in production lines.

Professional Applications & Engineering Value

This 5-40 UNC shoulder screw in 18-8 Stainless Steel addresses critical needs in precision machinery, automation systems, and electronic enclosures where alignment and strength are paramount. The hex socket head with knurling prevents cam-out during high-torque installation, while the Class 3A thread fit maintains consistent clamping force under vibration. The shoulder acts as a precise pivot or spacer, minimizing part wear in rotating assemblies. Its 70,000 psi tensile strength and corrosion-resistant material make it suitable for demanding applications like motor mounts, conveyor systems, and medical devices, ensuring long-term reliability without frequent maintenance.

Specification Summary & Compliance
