Grade 8 Coarse Thread Hex Cap Screws

A grade 8 bolt is distinguished by 6 radial lines on the head of the bolt and is most commonly found in demanding applications or those that require a higher strength. Coarse thread hex cap screws can be determined by threads with wide and deep ridges. Our grade 8 coarse thread fasteners are yellow zinc plated, making them rust resistant with a yellow/gold finish. All of our fasteners come bagged and labeled. If you are looking for large quantities, please contact us.
