Hex Bolts: Sizing, Grades, and Versatile Applications

This page provides a detailed overview of hex bolts, featuring a hexagonal head for easy tightening with wrenches. It covers key aspects such as sizing (diameter, length, thread pitch), thread types (fully vs. partially threaded), and strength grades (Grade 2, 5, 8 in imperial; 8.8, 10.9 in metric). Common applications across construction, automotive, and manufacturing are explored, along with tips for selecting the right hex bolt—matching material to load, environment, and installation needs. The content also explains how hex bolts differ from other fasteners, making it essential for anyone seeking versatile, high-torque fastening solutions.

Frequently Asked Questions

How to select the right hex bolt size for a project?

To select the right hex bolt size, consider the diameter (measured across the shank) and length (from the underside of the head to the tip). The diameter should match the hole size in the materials being joined, with a snug fit to prevent wobbling. The length should be sufficient to pass through all materials and engage fully with a nut (typically 1-1.5 times the diameter of threads beyond the nut). Also, consider the thread type (coarse or fine) based on the application—coarse threads are stronger in wood, while fine threads provide better holding in metal.

Mia Brown

In our commercial building project, these Grade 8 hex bolts were essential for joining steel beams. The tensile strength handled the heavy loads effortlessly, and the precise threading allowed for accurate torque application. We used the partially threaded version to maximize shear strength in the unthreaded shank, which was critical for structural integrity. The bolts came with matching Grade 8 nuts, ensuring compatibility and uniform performance. While they require careful torque checking, their reliability in high-load applications is unmatched.
