S-92610A126 5-40 x 3/8" ASTM A574 Torx Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 180,000 psi ensures reliable performance under high-stress conditions, reducing the risk of fastener failure in demanding applications.
• Superior corrosion resistance from the black-oxide finish extends service life and maintains integrity in harsh or humid industrial environments.
• Precise Class 3A thread fit provides consistent engagement and vibration resistance, minimizing loosening in machinery and assemblies.
• Torx Plus IP10 drive system offers enhanced torque transfer and reduced cam-out, allowing for efficient installation and maintenance with less tool wear.
• High hardness (Rockwell C39) increases wear resistance and durability, ensuring long-term reliability in repetitive or high-load scenarios.
• Coarse UNC threads enable quicker assembly and better performance in materials where fine threads may be prone to stripping.
• Full threading along the 3/8" length allows for flexible positioning and secure fastening across a range of material thicknesses.

Professional Applications & Engineering Value

Engineered for precision and endurance, this black-oxide alloy steel socket head cap screw addresses common industrial challenges such as vibration-induced loosening and environmental degradation. The 5-40 UNC coarse thread design ensures rapid installation and robust holding power in metals and composites, while the Torx Plus IP10 drive minimizes slippage during high-torque applications, reducing assembly time and tool damage. Ideal for machinery, automotive, and aerospace components, these screws provide consistent Class 3A thread fit for secure connections in dynamic loads. The black-oxide surface treatment adds a protective layer against rust and wear, making them suitable for outdoor or corrosive settings without compromising on 180,000 psi tensile strength.

Specification Summary & Compliance

This socket head cap screw adheres to ASTM A574 specifications, with precise Class 3A thread fit and UNC coarse threads for consistent dimensional accuracy. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance standards, ensuring environmental safety and regulatory alignment for global industrial use.
