S-97345A172 10-24 ASME B18.3 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh chemical and marine environments
• Enhanced load-bearing capability from 70,000 psi tensile strength and 35,000 psi shear strength for reliable performance under stress
• Precise component alignment enabled by the 2-1/2" shoulder with tight tolerances, reducing assembly errors
• Secure fastening in coarse-thread applications with 10-24 UNC threads and Class 3A fit for vibration resistance
• Non-slip installation and removal thanks to the knurled socket head design for improved tool grip
• Long-term operational reliability backed by Rockwell B79 hardness for wear resistance in dynamic applications
• Global regulatory compliance meeting ASME B18.3, RoHS, and REACH standards for safe, worldwide use

Professional Applications & Engineering Value

This 316 stainless steel shoulder screw delivers critical engineering solutions in demanding sectors like automation, machinery, and precision equipment. Its 2-1/2" shoulder length with minimal tolerance ensures exact pivot points and alignment in assemblies, eliminating misalignment issues. The 10-24 UNC coarse threads with Class 3A fit provide robust engagement in softer materials or high-vibration settings, while the knurled socket head enhances torque transmission during installation. Manufactured to ASME B18.3 specifications, it offers consistent performance in corrosive environments, supported by 70,000 psi tensile strength for heavy-duty applications.

Specification Summary & Compliance

This shoulder screw adheres to Class 3A thread fit for precise engagement, with shoulder diameter tolerance of -0.004" to -0.002" and length tolerance of -0.005" to 0.005". It conforms to ASME B18.3 manufacturing standards and is fully RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, ensuring environmental safety and material integrity.
