S-95446A642 6-32 Shoulder Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with 360 Brass material, ideal for harsh environments and electrical applications.
• Precise alignment and reduced assembly wear due to the smooth shoulder with tight diameter and length tolerances.
• Superior strength and durability from a 40,000 psi tensile strength and Rockwell B55 hardness.
• Reliable, vibration-resistant fastening ensured by the UNC coarse thread profile and Class 2A thread fit.
• Secure, flush installation with a standard hex socket head for a clean finish and high torque application.
• Compliance with major environmental regulations, including RoHS 3 and REACH, for global supply chain integration.
• Optimized for automated assembly with consistent dimensions and a right-hand thread direction.

Professional Applications & Engineering Value

This 360 Brass shoulder screw is engineered to solve critical challenges in precision assembly. The UNC coarse thread and Class 2A fit provide excellent engagement and resistance to loosening under vibration, common in machinery and automotive subsystems. The smooth, precise shoulder acts as a pivot, bearing surface, or locator, ensuring accurate alignment of components like gears, pulleys, and linkages without the need for additional bushings. Made from brass, it offers inherent corrosion resistance and non-magnetic properties, making it indispensable in electrical enclosures, marine hardware, and sensitive instrumentation. This combination of material and mechanical precision reduces maintenance, prevents galvanic corrosion when used with other non-ferrous metals, and extends the service life of the assembled product.

Specification Summary & Compliance

This screw features a 6-32 UNC thread with a Class 2A tolerance for consistent, reliable fit. The shoulder maintains a precise diameter and length tolerance for accurate locating. Manufacturing and material compliance is confirmed with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006).
