S-93996A847 10-32 Shoulder Screws

Key Features & Benefits at a Glance

• Vibration-resistant locking: Integrated nylon patch thread locker maintains secure fastening in temperatures from -70° to 250°F, reducing maintenance in dynamic environments.
• High-strength durability: 70,000 psi tensile strength and Rockwell B55 hardness ensure reliable performance under heavy loads and repeated use.
• Precision alignment: 1/2" shoulder with tight length tolerance (0" to 0.002") provides accurate component positioning and smooth rotational movement.
• Corrosion resistance: 18-8 stainless steel construction offers excellent protection against rust and degradation in harsh industrial conditions.
• Secure thread engagement: Class 2A thread fit with 10-32 UNF fine threads delivers consistent clamping force and reduces loosening risks.
• Easy installation: Hex socket head design allows for high-torque application with standard tools, speeding up assembly processes.
• Regulatory compliance: Meets RoHS 3 and REACH standards, ensuring safe use in regulated industries and global markets.

Professional Applications & Engineering Value

This 10-32 UNF shoulder screw is engineered to solve critical alignment and vibration challenges in precision assemblies. The 18-8 stainless steel material provides inherent corrosion resistance, ideal for machinery exposed to moisture, chemicals, or outdoor elements. The 1/2" shoulder length with precise tolerances acts as a reliable axle or pivot point in rotating components, eliminating the need for additional bushings in applications like conveyor systems, robotic arms, and electrical motor mounts. The nylon patch thread locker secures the fine thread fastening against shock and vibration, maintaining integrity in automotive, aerospace, and industrial equipment where thermal cycling from -70° to 250°F is common. By combining hex socket head drive efficiency with Class 2A thread fit accuracy, this screw reduces assembly errors and extends service life in high-stress environments.
