S-98637A286 8-32 x 1/4" MS51963-35 Set Screws

Key Features & Benefits at a Glance

• Exceptional holding power with Class 3A thread fit for precise, vibration-resistant fastening in critical assemblies.
• Superior corrosion resistance due to cadmium plating, extending service life in harsh industrial environments.
• High mechanical strength from alloy steel and Rockwell C45 hardness, preventing deformation under heavy loads.
• Secure, non-slip engagement with the cup point tip design, ensuring components stay firmly locked in position.
• Easy installation and removal using a standard 5/64" hex key, saving time during assembly and maintenance.
• Reliable performance in demanding applications, backed by compliance with MS51963-35 specifications.
• Versatile coarse UNC threading for quick assembly and robust connections in various materials.

Professional Applications & Engineering Value

This 8-32 UNC Class 3A cup point set screw is engineered to address common industrial challenges like component slippage and fastener failure. Made from cadmium-plated alloy steel, it resists corrosion and wear, making it ideal for machinery, automotive, and aerospace applications where environmental factors are a concern. The coarse thread spacing and right-hand thread direction facilitate rapid installation while maintaining a tight grip. Its headless design allows for flush mounting in confined spaces, and the cup point tip bites into surfaces for enhanced security, reducing the need for frequent retightening. This combination of material durability and structural precision ensures long-term reliability in high-stress environments, supporting efficient production and reduced downtime.
