Hex bolts have a hexagonal head, are partially threaded and are used in machinery and construction applications. You can find out more in our [guide to hex bolts](/web/content/discovery/ideas-and-advice/hex-bolts-guide).

**Uses**

They can be used with a nut or in a tapped hole and are tightened with a [hex key](/web/c/tools/spanners-sockets/hex-keys-sets/) 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.
