S-97832A338 10-24 ASME B18.3 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh environments and extended service life.
• Exceptional mechanical strength offering 70,000 psi tensile and 35,000 psi minimum shear strength for reliable performance under high stress.
• Precise alignment and smooth rotation enabled by the 1" shoulder with controlled diameter tolerance, reducing wear on mating parts.
• Secure and reliable fastening with Class 3A thread fit for tight tolerances and vibration resistance in critical assemblies.
• Enhanced installation grip from the knurled socket head and 5/32" hex drive, preventing tool slippage during torque application.
• Broad industrial compatibility due to compliance with ASME B18.3 standards and UNC coarse thread for quick assembly.
• Environmentally compliant design meeting RoHS 3 and REACH regulations for safe use in regulated markets.

Professional Applications & Engineering Value

This 10-24 UNC shoulder screw is engineered to address common challenges in precision machinery, such as misalignment and component wear. The 18-8 Stainless Steel material provides excellent corrosion resistance, making it suitable for applications in humid or chemically aggressive environments, including food processing, marine, and outdoor equipment. The 1" shoulder length acts as a precise pivot or spacer, ensuring accurate alignment of moving parts like gears, bearings, and linkages, which minimizes friction and extends assembly life. Combined with the Class 3A thread fit and coarse UNC thread, it offers quick, secure fastening that withstands vibrations in dynamic systems. The knurled socket head enhances grip for efficient installation, reducing downtime in automated or high-volume production settings.
