Professional Applications & Engineering Value

These 10-24 UNC socket head cap screws deliver critical engineering advantages in industrial applications where reliability and precision are paramount. The zinc-plated alloy steel construction combats corrosion in harsh environments, while the 170,000 psi tensile strength prevents elongation and failure under heavy loads. The Class 3A thread fit and coarse UNC thread form provide superior resistance to vibration loosening in machinery, automotive, and equipment assembly. The partially threaded design with 3/4" thread length allows for precise positioning and clamping in jigs, fixtures, and structural components. With 5/32" hex drive compatibility, these fasteners enable efficient installation in confined spaces where wrench clearance is limited, making them ideal for maintenance and manufacturing applications requiring dependable, high-strength fastening solutions.

Specification Summary & Compliance
