Product Description

RS PRO 292-221 is a high-strength black steel hex socket cap screw featuring a 3/8 inch diameter and 1.25 inch length designed in accordance with ANSI B18.3 standards. This Grade 8.8 screw uses a hex drive type and is thermo forged to achieve 15-18% increased resistance to fatigue failure, making it stronger than conventional screws of similar size.

Manufactured with high tensile alloy steel, the screw offers superior mechanical properties compared to carbon steel, ensuring durability in demanding industrial environments. The hex socket cap head design provides a smooth contour surface, enhancing safety and ease of use in assembly operations.

This socket cap screw is widely used in machine tooling, security guarding, electronic devices, domestic and medical equipment, as well as construction applications. It requires a hex key for installation, enabling a secure and vibration-resistant fastening solution.

The screw is crafted with precise threads conforming to the imperial UNC standard, ensuring compatibility with standard fasteners. The black finish adds corrosion resistance, extending the service life of the fastener in challenging environments.
