S-97381A206 8-32 Shoulder Screws

Key Features & Benefits at a Glance

• High strength-to-weight ratio with 40,000 psi tensile and 20,000 psi shear strength, ideal for reducing component weight without sacrificing durability in assemblies.
• Precise Class 3A thread fit ensures tight, reliable engagement and minimizes the risk of cross-threading during installation in demanding applications.
• Knurled hex socket head provides superior grip and slip resistance, allowing for secure torque application with standard 3/32" hex tools.
• Corrosion-resistant 6061 aluminum offers excellent machinability and longevity in environments where weight and oxidation resistance are critical.
• Standard UNC coarse threading enables quick assembly and disassembly, reducing labor time and improving maintenance efficiency.
• Consistent shoulder diameter and length with tight tolerances ensure accurate alignment and smooth rotation for pivoting or spacing components.
• Full compliance with RoHS 3 and REACH regulations, making it suitable for global industrial markets with strict environmental standards.

Professional Applications & Engineering Value

This 6061 aluminum shoulder screw is engineered to address common challenges in precision assemblies, such as misalignment and component wear. The Class 3A thread fit and UNC coarse thread provide reliable fastening in dynamic applications, from machinery pivots to electronic enclosures, where vibration resistance is crucial. The knurled socket head enhances installation security, reducing tool slippage and potential damage. With a 3/16" shoulder length and controlled tolerances, it ensures exact positioning for bearings, gears, or linkages, minimizing play and improving operational accuracy. Its aluminum construction offers an optimal balance of strength and lightweight properties, ideal for aerospace, automation, and consumer electronics where weight reduction and corrosion resistance are priorities.
