• Space-saving low-profile socket head with hex drive allows for installation in tight spaces and provides secure, high-torque driving.
• Reliable and quick assembly with 8-32 UNC coarse threads and Class 2A fit, offering consistent engagement and vibration resistance.
• Compliance with major regulations including RoHS 3 and REACH, ensuring safety and environmental standards are met for global supply chains.
• Versatile right-hand thread design with coarse spacing for efficient fastening in a wide range of industrial applications.

Professional Applications & Engineering Value

This precision shoulder screw is engineered to solve critical alignment challenges in machinery, automation, and assembly fixtures. The 18-8 Stainless Steel construction, enhanced by a passivated finish, provides excellent resistance to corrosion and wear, making it suitable for demanding environments like manufacturing and electronics. The low-profile socket head with a hex drive enables easy access in confined spaces, while the precisely machined shoulder (3/16" diameter, 5/16" length) acts as a pivot or spacer, reducing misalignment and component wear. With 8-32 UNC coarse threads and a Class 2A thread fit, it ensures secure, vibration-resistant fastening, improving overall equipment reliability and reducing maintenance needs in industrial applications.

Specification Summary & Compliance

This shoulder screw adheres to Class 2A thread fit for consistent assembly and features UNC coarse threads (8-32 size) with precise dimensional controls, including shoulder diameter tolerance of -0.001" to 0" and shoulder length tolerance of 0" to 0.002". Manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, it meets stringent environmental and safety standards for industrial use.
