S-95446A340 8-32 Shoulder Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 360 Brass construction, ideal for harsh environments and reducing maintenance costs
• Precise component alignment ensured by the smooth, accurately machined shoulder with tight diameter and length tolerances
• High mechanical strength offering 40,000 psi tensile and 22,000 psi shear strength for reliable performance in demanding applications
• Superior wear resistance from a Rockwell B55 hardness, extending the service life of the screw and mating parts
• Easy and secure installation with a standard hex socket drive, preventing cam-out and allowing for high torque application
• Guaranteed thread interchangeability with a Class 2A fit and standard 8-32 UNC coarse thread, simplifying assembly and sourcing
• Compliance with global environmental regulations including RoHS 3 and REACH, ensuring suitability for international markets

Professional Applications & Engineering Value

This brass shoulder screw is engineered to solve critical alignment and wear challenges in precision assemblies. The 360 Brass material provides excellent corrosion resistance, making it ideal for use in electrical components, marine hardware, and plumbing systems where exposure to moisture is a concern. The precise shoulder acts as a reliable pivot point or spacer, maintaining exact positioning in machinery, rotating assemblies, and linkages. The combination of a Class 2A thread fit and a coarse UNC thread ensures quick assembly and vibration resistance, while the hex socket drive allows for installation in confined spaces. This design directly addresses the need for durable, non-sparking, and corrosion-resistant fasteners in industrial applications, reducing downtime and improving long-term assembly integrity.

Specification Summary & Compliance

This shoulder screw features an 8-32 UNC coarse thread with a Class 2A fit for standard thread engagement and interchangeability. The shoulder is manufactured to precise tolerances, with a diameter of 3/16" (-0.002" to 0") and a length of 5/8" (0" to +0.003"). The product is compliant with RoHS 3 (2015/863/EU) under exemption 6(c) for lead in copper alloy and is REACH (EC 1907/2006) compliant, meeting stringent environmental and safety standards for industrial use.
