Hex nuts have an interior thread that is used to screw the nut onto a hex bolt with matching thread. The use of hex nuts provides a strong, secure join with the bolt that is able to withstand high wear, stress and strain. As a result, hex nuts and bolts are used in many industrial applications that require a strong join that will hold under high wear, movement and heavy loads. Common uses include machinery, engines, motors, industrial equipment and furniture.
