About Hex Head Screws and Bolts

Choose a hex head fastener with the right threading, thread size, material, and strength for your equipment.

Steel Heavy Hex Head Structural Screws

Partially

Threaded

Secure structural joints, such as mating I-beams, columns, and joists. With a head that's about 10% wider than standard hex head screws, these handle heavier loads by distributing them over a larger area. The head also has six flat sides to keep wrenches and sockets from slipping and rounding off the drive.

Length is measured from under the head.

High-Strength Fastener—Commonly used to fasten components in valves, pumps, motors, and other high-stress applications. These screws have a tensile strength of 125,000 to 160,000 psi.

Hot-Dipped Galvanized Steel—The strength of steel with the rust resistance of stainless steel. These screws are an economical alternative to 18-8 stainless steel in wet and outdoor environments, but they won't hold up to salt water and chemicals. The galvanized finish is thicker than other types of coatings, so the threads may be more likely to stick during installation. You can only mate these screws with hot-dipped galvanized nuts.

Grip Length—Screws with a grip length have a precisely measured unthreaded section under the head, called a grip. It's stronger than the threaded section, so you can place it in joints exposed to sideways forces.
