S-90332A110 2-56 x 1/4" High-Profile Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength (70,000 psi) ensures reliable performance under high-stress conditions, reducing the risk of fastener failure
• Superior corrosion resistance from 18-8 stainless steel construction maintains integrity in harsh environments and extends service life
• Precise Class 3A thread fit delivers tighter tolerances for secure fastening and vibration resistance in critical assemblies
• High-profile socket head design with 5/64" hex drive provides maximum torque transmission and prevents tool slippage
• Fully threaded shank offers consistent clamping force along the entire 1/4" length for uniform load distribution
• Rockwell B84 hardness rating maintains thread integrity and prevents deformation during installation and use
• Coarse UNC thread pattern enables quick assembly and disassembly while resisting clogging in industrial applications

Professional Applications & Engineering Value

This 2-56 UNC socket head cap screw delivers critical engineering advantages where space constraints and high-strength requirements intersect. The 18-8 stainless steel composition provides excellent corrosion resistance for machinery exposed to moisture, chemicals, or outdoor elements, while the Class 3A thread fit ensures precise engagement in tapped holes, eliminating play and maintaining alignment in precision equipment. The high-profile socket head design allows for higher torque application compared to standard fasteners, making it ideal for industrial fasteners in automotive, aerospace, and manufacturing applications where vibration resistance is paramount. The coarse thread configuration prevents cross-threading during rapid assembly operations, while the fully threaded construction provides consistent clamping force across the entire engagement length.

Specification Summary & Compliance

This socket head cap screw features 2-56 UNC coarse threads with Class 3A fit for precision engagement, manufactured to inch system specifications. The fastener maintains dimensional accuracy with a head diameter of 9/64", head height of 0.129", and overall length of 1/4". Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and restricted substance adherence for global industrial applications.
