• Precise alignment and secure fit due to Class 3A thread fit and standard shoulder fit, reducing assembly errors.
• Easy installation and removal with a hex socket drive and knurled head for improved grip and torque application.
• Reliable performance in regulated industries as it is RoHS 3 and REACH compliant, meeting environmental and safety standards.
• Consistent dimensional accuracy with tight tolerances on shoulder diameter and length, ensuring repeatable assembly.
• Versatile coarse UNC threading for quick engagement and resistance to vibration in dynamic applications.

Professional Applications & Engineering Value

This 8-32 UNC shoulder screw is engineered to address critical challenges in industrial settings, such as misalignment and corrosion-induced failure. The 316 Stainless Steel material, combined with a Black Oxide finish, provides exceptional resistance to chemicals and moisture, extending service life in machinery, automotive, and marine applications. The hex socket head and knurled texture facilitate secure tool engagement, minimizing slippage during high-torque installations. With a Class 3A thread fit and precise shoulder dimensions, it ensures accurate positioning in assemblies, reducing wear and maintenance costs. Ideal for pivots, spacers, and rotating components, this screw delivers reliable performance where high tensile strength and regulatory compliance are paramount.

Specification Summary & Compliance
