S-97832A245 2-56 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh industrial environments
• Precise component alignment ensured by Class 3A thread fit and standard shoulder fit for reduced assembly errors
• High mechanical reliability with 70,000 psi tensile strength and 35,000 psi shear strength for demanding applications
• Secure installation and removal facilitated by 5/64" hex drive and knurled socket head design
• Consistent performance in automated systems due to Rockwell B55 hardness and coarse UNC thread spacing
• Environmental compliance assurance meeting RoHS 3 and REACH regulations for global supply chain compatibility
• Extended service life from durable shoulder design with tight diameter and length tolerances

Professional Applications & Engineering Value

This 18-8 Stainless Steel shoulder screw delivers critical precision in mechanical assemblies where component alignment and rotational stability are paramount. The Class 3A thread fit combined with UNC coarse threads provides superior engagement in metals and plastics, reducing cross-threading risks in high-volume production. The knurled socket head with 5/64" hex drive maintains torque integrity during repeated maintenance cycles, while the 7/8" shoulder length acts as a precise axle or pivot in machinery, conveyor systems, and electronic enclosures. Engineered for 70,000 psi tensile strength, it withstands vibrational stresses in automotive jigs, robotics, and packaging equipment where shear strength requirements exceed 35,000 psi.

Specification Summary & Compliance
