S-90128A944 10-32 x 5/8" ASTM A574 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Superior tensile strength of 170,000 psi ensures reliable performance in high-stress applications, reducing the risk of fastener failure.
• Exceptional thread precision with Class 3A fit provides tighter tolerances for secure, vibration-resistant connections in critical assemblies.
• Corrosion-resistant zinc plating on alloy steel enhances durability and extends service life in demanding industrial environments.
• Fine thread spacing (UNF) offers improved adjustment accuracy and superior holding power compared to coarse threads.
• Hex socket drive design allows for high-torque installation and removal in confined spaces, improving assembly efficiency.
• Full threading along the 5/8" length enables maximum engagement with mating components for enhanced load distribution.
• Consistent hardness (Rockwell C37) maintains dimensional stability and prevents deformation under heavy loads.

Professional Applications & Engineering Value

Engineered for precision industrial fastening applications, these socket head cap screws deliver exceptional performance where reliability is critical. The zinc-plated alloy steel construction provides excellent corrosion resistance while maintaining the 170,000 psi tensile strength required for heavy-duty machinery, automotive components, and precision equipment. The 10-32 UNF fine thread configuration ensures secure fastening in materials prone to vibration loosening, while the Class 3A thread fit guarantees precise engagement for applications demanding minimal clearance and maximum reliability. The hex socket drive enables efficient installation in space-constrained environments, making these fasteners ideal for maintenance operations and production line assemblies where accessibility is limited.
