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

What grades of hex bolts are available, and what do they indicate?

Hex bolts are available in various grades that indicate their strength and material composition. In the US, common grades include Grade 2 (low-carbon steel, general-purpose), Grade 5 (medium-carbon alloy steel, higher strength, used in automotive and structural applications), and Grade 8 (high-carbon alloy steel, highest strength, for critical high-load joints). Metric grades, like 8.8 and 10.9, are also common, where the first number indicates tensile strength in MPa divided by 100, and the second is the ratio of yield strength to tensile strength. Higher grades mean greater load-bearing capacity.

Olivia Wilson

As a DIYer on a budget, these carbon steel hex bolts are perfect for my garage projects. The Grade 2 steel is sufficient for light to moderate loads, like assembling shelves or securing brackets. The uncoated finish is fine for indoor use, and I can paint them to match my projects. The bolts are widely available at local stores, so I never have to wait for shipping. While they're not suitable for heavy-duty or outdoor use, they're a great value for everyday DIY tasks where cost is a priority.
