Grade 8 Fine 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. Fine thread hex cap screws can be determined by threads with more narrow and shallow ridges. Our grade 8 fine thread fasteners are yellow zinc plated, making them rust resistant with a yellow/gold finish. All of our fasteners come bagged and labeled.
