S-90128A909 3/4"-10 x 2" ASTM A574 Alloy Steel Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional tensile strength of 170,000 psi ensures reliable performance in high-stress applications, reducing the risk of fastener failure.
• Superior corrosion resistance from zinc plating protects against rust and extends service life in harsh industrial environments.
• Precise Class 3A thread fit provides tighter tolerances for secure, vibration-resistant assemblies, minimizing loosening over time.
• High hardness rating (Rockwell C37) offers excellent wear resistance, maintaining thread integrity through repeated use.
• Coarse UNC threads enable quicker installation and are less prone to clogging in dirty or debris-filled conditions.
• 5/8" hex drive design allows for high torque application with standard tools, ensuring efficient and secure fastening.
• Full threading along the 2" length provides maximum grip and adjustability in a variety of material thicknesses.

Professional Applications & Engineering Value

This Socket Head Cap Screw is engineered to address critical challenges in heavy machinery, automotive, and construction sectors where vibration resistance and high tensile loads are common. The zinc-plated alloy steel construction combats corrosion in outdoor or chemically exposed settings, while the coarse UNC thread ensures reliable engagement in softer materials or where rapid assembly is required. Its Class 3A thread fit and fully threaded design deliver consistent clamping force, preventing joint failure in dynamic applications. Ideal for industrial fastening that demands both durability and compliance with stringent industry specifications.

Specification Summary & Compliance

Manufactured to ASTM A574 specifications, this screw features a Class 3A thread fit with 3/4"-10 UNC coarse threads and a right-hand thread direction. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental and safety standards are met for global industrial use.
