S-97345A437 10-24 ASME B18.3 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 ensured by Class 3A thread fit and standard shoulder for reduced assembly play
• High mechanical strength with 70,000 psi tensile strength and 35,000 psi shear strength for demanding applications
• Secure, slip-resistant installation via knurled hex socket head and 1/8" hex drive for reliable torque transfer
• Optimized for high-volume assembly with coarse 10-24 UNC threads enabling faster installation and reduced cross-threading risk
• Regulatory compliance assurance meeting ASME B18.3 specifications and environmental standards (RoHS 3, REACH)
• Consistent dimensional accuracy with tight shoulder diameter and length tolerances for repeatable positioning

Professional Applications & Engineering Value

This 316 stainless steel shoulder screw delivers critical engineering solutions where precision alignment and corrosion resistance are paramount. The Class 3A thread fit minimizes backlash in rotating assemblies, while the standard shoulder diameter provides exact bearing surfaces for gears, linkages, and pivoting mechanisms. The knurled hex socket head prevents tool slippage during high-torque installation in confined spaces. Ideal for precision machinery, chemical processing equipment, and marine applications, this fastener maintains dimensional stability under load with its 70,000 psi tensile strength. The coarse UNC threads ensure rapid assembly in production environments while the 316 stainless steel material resists pitting in chloride-exposed applications.
