Constructed from grade 5 (GR5) alloy steel, the 920555 Hex Head Capscrew offers high durability and corrosion resistance, making it suitable for demanding environments. The zinc plating (ZN PLT) provides additional corrosion protection, extending the component’s service life in outdoor or humid conditions.

The screw has a hex head profile measuring approximately 0.75 inches across flats, allowing for torque application with standard tools. It features a fully threaded shank, which enhances clamp load distribution and shear strength. The threads conform to a unified national coarse (UNC) thread standard, ensuring compatibility with corresponding nuts and threaded components.

Dimensions include a 1/2-inch diameter threaded shank, with a thread pitch of 13 threads per inch, and a length of 2 1/2 inches from the bottom of the head to the end of the shank. The weight of each screw is approximately 0.1 pounds, enabling efficient handling and assembly.

Key features of the 920555 Hex Head Capscrew include its corrosion-resistant zinc finish, precision-machined threads for accurate fit, high-strength alloy steel construction, and compatibility with standard hex sockets. It is ideal for use in machinery assembly, structural connections, and equipment maintenance where reliable fastening is critical.

This product is suitable for professionals and industrial maintenance personnel seeking durable fasteners that provide consistent performance under stress. Its robust construction makes it a preferred choice for demanding applications in manufacturing, construction, and mechanical systems.

Included in each package is the individual 920555 Hex Head Capscrew. There are no additional accessories or tools included. The screw is sold as a single unit or in bulk packs, depending on supplier options.
