S-91273A122 10-24 Shoulder Screws

Key Features & Benefits at a Glance

• Corrosion-resistant 18-8 stainless steel ensures long-term reliability in harsh or humid industrial environments
• High tensile strength of 70,000 psi provides exceptional load-bearing capacity for demanding mechanical assemblies
• Knurled socket head with hex drive offers superior grip and prevents tool slippage during installation
• Class 2A thread fit with UNC coarse threading guarantees smooth, precise engagement and consistent fastening performance
• Rockwell B55 hardness rating maintains structural integrity under repeated stress and vibration
• RoHS 3 and REACH compliance meets stringent environmental regulations for global supply chain compatibility
• 3/16" shoulder diameter with tight tolerances enables accurate alignment in precision machinery and rotating components

Professional Applications & Engineering Value

This 10-24 UNC shoulder screw delivers critical engineering solutions where precise component alignment and rotational stability are paramount. The 18-8 stainless steel construction combats corrosion in manufacturing equipment, food processing machinery, and outdoor applications, while the knurled socket head design prevents cam-out during high-torque assembly. With 70,000 psi tensile strength and Class 2A thread fit, it maintains clamping force in vibrating systems and maintains dimensional accuracy in jigs, fixtures, and bearing mounts. The 3/16" shoulder length acts as a precision spacer or pivot point, eliminating the need for additional bushings in automated systems and CNC equipment.
