    Hex Bolts

    Hex bolts have a hexagonal head, are partially threaded and are used in machinery and construction applications. You can find out more in our complete guide to hex bolts.

    Uses

    They can be used with a nut or in a tapped hole and are tightened with a hex key or wrench.

    Hexagon bolts are suitable for heavy duty fastening applications such as on bridges, buildings and road structures.

    Materials used for Hex Bolts

    • Brass is a copper alloy which is more expensive than steel. It gives a better level of corrosion resistance.
    • Stainless Steel gives good corrosion resistance and can be used outdoors. There are two different types of stainless steel: A4 (316) has a higher corrosion resistance than A2 (304). Both grades can handle low and high temperatures.
    • Steel comes in different grade and strengths. A higher number indicates a stronger, more hardened material.
    • Zinc Plated Steel is used on bolts for indoor use and gives a moderate corrosion resistance.
