S-93996A215 6-32 Shoulder Screws

Key Features & Benefits at a Glance

• Vibration-resistant locking with permanent nylon patch that maintains secure fastening in demanding conditions from -70° to 250° F
• Exceptional corrosion resistance thanks to 18-8 stainless steel construction, ideal for harsh industrial environments
• Precise alignment and positioning enabled by the precisely machined shoulder with tight diameter and length tolerances
• High strength performance with 70,000 psi tensile strength and Rockwell B55 hardness for heavy-duty applications
• Reliable thread engagement through Class 2A thread fit and coarse UNC threading for quick assembly
• Secure socket drive providing superior torque transmission and reduced risk of stripping compared to standard drives
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global industrial use

Professional Applications & Engineering Value

This 6-32 UNC shoulder screw delivers critical engineering solutions where vibration resistance and precise component positioning are paramount. The 18-8 stainless steel construction provides excellent corrosion resistance for machinery operating in humid or chemically aggressive environments, while the permanent nylon patch thread locker eliminates the need for additional locking hardware in assemblies subject to constant motion or thermal cycling. The precisely machined shoulder with tight tolerances ensures accurate alignment in pivoting mechanisms, bearing assemblies, and precision equipment, reducing wear and maintaining operational accuracy. With its socket head design and coarse UNC threading, installation becomes more efficient in production lines while providing reliable performance in automotive, aerospace, and industrial manufacturing applications where fastener failure is not an option.

Specification Summary & Compliance

This shoulder screw features Class 2A thread fit per UNC standards with precise shoulder diameter tolerance (-0.001" to 0") and shoulder length tolerance (0" to 0.002"). Manufactured from 18-8 stainless steel with Rockwell B55 hardness and 70,000 psi tensile strength. The fastener is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and global market acceptability for industrial applications.
