Hex bolts, also known as machine bolts, six-sided heads, or hex-cap screws, are fastening tools designed to join a great range of material types in engineering applications. These hexagonal bolts are standard fasteners in various industries with their forged heads and are easily installed using automated or manual tools like socket wrenches. They come in different diameters, types, and materials with effective fastening performances in pre-tapped holes. Hexagon bolts come as either threaded or non-threaded with versatile machinery and construction applications over wood and metals with distinctive head shapes.
How Does Hex Bolt Work?
Hex bolts allow accessible fastening applications with the help of hex bolt wrenches, spanners, sockets, and hex keys in pre-tapped holes. They also allow easy loosening and tightening with their structural configuration. The compatible tool fits precisely the bespoke bolts and functions per users’ applications needs.
Materials for Hex Bolts
Hexagonal bolts are constructed from splendid durable, and strong materials that make bolts highly resistant to various environmental factors and include steel, stainless steel, and brass with different plating like zinc-plated steel. Brass provides a high level of resistance to corrosion. Like brass, stainless steel also offers excellent corrosion resistance and comes in two versions with distinct corrosion-resistance grades suitable for outdoor applications and to withstand high temperatures. Moreover, steel also comes in varied strengths and grades, while zinc-plated steel is ideal for indoor applications with moderate resistance against corrosion.
Types of Hex Bolts
Different hex bolt types are available, each of them characterized based on their types, sizes, and shapes to be used with suitable applications and environments. The two common types include:
- Partially-Threaded Hex Bolts – Such hexagonal bolts come as threaded from partially down the length of the bolt to the end with significant resistance levels. The design ensures no weak spots and prevents strain on the shank’s unthreaded part.
- Fully-Threaded Hex Bolts – Unlike threaded hex bolts, fully threaded hexagon bolts are threaded from the bolt’s end to the head. They are more robust, spread the pressure over the whole bolt’s length, and are suitable for heavy-duty pre-threaded hole fastening applications.
Typical Applications of Hex Bolt
Hex head bolts feature remarkable specifications and suit fastening for metal, wood, and other scenarios in a range of industrial and construction applications. They are widely employed in the following:
- Construction/Under Construction Projects
- Repair and Mending Applications
- Woodworking Applications
- Machinery Integration
- Automobiles
- Control System
- Engineering Applications
- Hospitals, Roads, Bridges, and Building Constructions.
