If you are in the automobile industry, engineering sector, or run a construction company, you must have heard of hex head bolts. Hex bolts are unique fixing solutions popular with professionals and handypersons alike. The sections below will tell you about the applications of hex bolts and guide you into choosing the best ones for your projects.

Essentials of Hex Bolts

Hex bolts get their name from their six-sided (hexagonal) heads. They come with an inherent design that allows them to function effectively in many industries, including engineering, shipping and docking, and construction. And, their versatility makes them ideal for numerous fixing jobs that require super-strong fasteners with optimum tensile strength. One of the main reasons most specialists often pick hex bolts is their six-sided heads facilitate convenient gripping. That means, when you work with these bolts, you can tighten or loosen them easily from any angle or direction, using all kinds of tightening tools like spanners. Plus, you can use them to fasten various materials, including wood and metal.

What to Consider When Choosing Hex Bolts

The following factors should guide your choice of hex bolts:


Plastic and metals are the primary materials used in bolt-making. Plastic bolts are ideal for applications that require corrosion, chemical, and electrical resistance in bolts. Otherwise, you should opt for metallic bolts anytime you need optimum strength and security. Some of the metals used to make hexagonal bolts include steel, copper, brass, and aluminum. Stainless steel is arguably the most common hex bolt material. It provides unrivaled strength and corrosion resistance. That makes stainless steel hex bolts suitable fasteners for applications where other options rust too quickly due to high salinity and moisture content.  


Hex bolts come with different body diameters, head thickness, and dimensions across the flats and corners. All these account for different sizes. The primary rule is to use the bolt size recommended by a manufacturer when you fasten a specific product. Furthermore, factor in the clamping force required in the joint that needs bolting.


When it comes to threads, there are two main hex bolt options to choose from: fully threaded and plain/partial threaded. If you plan to use hex bolts to fasten heavy-duty objects and materials, fully threaded should be your go-to fastening solution. On the other hand, if your applications demand optimum alignment and resistance, plain or partial threaded hexagonal bolts can do the job nicely. Plus, these bolts come with unthreaded planks below the bolt head, making them strong enough to fasten objects that require massive force to hold together.

Where to Buy Hex Bolts?

Once you have decided your industrial applications need hex bolts, the next step is purchasing them. Ensure you buy your fasteners and other accessories from a reputable company that guarantees high-quality products.
