S-90324A068 8-32 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction for long-lasting performance in harsh industrial environments
• Precise component alignment enabled by the 3/4" shoulder length with tight tolerances for stable assembly operations
• High mechanical strength delivering 70,000 psi tensile and 35,000 psi shear capacity for demanding applications
• Secure left-hand threading with Class 3A UNC coarse threads providing reliable fastening in reverse-rotation scenarios
• Easy installation and removal through hex socket drive and knurled head design for improved tool grip
• Consistent hardness at Rockwell B55 ensuring dimensional stability under load
• Regulatory compliance meeting RoHS 3 and REACH standards for safe use across regulated industries

Professional Applications & Engineering Value

This 18-8 Stainless Steel shoulder screw addresses critical alignment and corrosion challenges in precision assemblies. The 3/4" shoulder length with controlled diameter tolerance maintains exact component spacing in machinery, while the left-hand UNC coarse threads prevent loosening in counter-rotating systems. Engineered for 70,000 psi tensile strength, it sustains structural integrity in vibratory equipment and automated fixtures. The knurled socket head combined with hex drive ensures secure tool engagement during installation, reducing slippage in confined spaces. Ideal for robotics, conveyor systems, and optical mounts where corrosion-resistant shoulder screws must maintain precision under mechanical stress.

Specification Summary & Compliance

Manufactured to Class 3A thread fit standards with UNC coarse threading (8-32 size). Shoulder diameter maintains -0.004" to -0.002" tolerance, while shoulder length holds ±0.005" precision. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material traceability.
