S-94035A204 8-32 MS51576-10, NASM51576 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction and passivated finish for extended service life in harsh environments.
• Precise component alignment ensured by a 3/16" shoulder diameter with a tight tolerance of -0.001" to 0" for reduced assembly play and vibration.
• High-strength performance offering 70,000 psi tensile strength and Rockwell B55 hardness for demanding mechanical applications.
• Reliable thread engagement with a Class 2A fit on the 8-32 UNC coarse thread, promoting easier assembly and consistent clamping force.
• Secure and streamlined installation using a standard hex socket (3/32" drive) for high torque application and a smooth, low-profile head.
• Compliance with stringent industry standards including MS51576-10, RoHS 3, and REACH, ensuring material quality and environmental safety.
• Durable shoulder section with a 3/8" length and precise tolerance (0" to 0.002") for stable pivoting, locating, or bearing surfaces.

Professional Applications & Engineering Value

This 8-32 UNC shoulder screw is engineered to solve critical alignment and durability challenges in industrial applications. The 18-8 stainless steel material, enhanced by a passivated finish, provides excellent resistance to oxidation and chemical exposure, making it ideal for machinery, automotive assemblies, and electronic enclosures operating in corrosive settings. The precise shoulder diameter and length act as a built-in locating dowel, eliminating the need for additional alignment pins and reducing assembly time. The coarse UNC thread and Class 2A fit ensure rapid, reliable fastening even in vibrating environments, while the hex socket drive allows for high-torque installation in confined spaces. This combination of material properties and dimensional accuracy delivers long-term reliability, reduces maintenance cycles, and enhances the performance of precision mechanisms.
