Heavy hex bolts have larger and thicker heads than regular or standard hex bolts, and are commonly used in a wide variety of applications. These fasteners are available in different sizes, both lengths and diameters, although all come with a hexagon head. A325 specifications call for heavy hex bolts, but with a shorter thread compared to other variants.
Dimensions: Available in all standard sizes.
