Grade 8 yellow zinc hex cap screw

A Grade 8 Yellow Zinc Hex Cap Screw is a high-strength fastener made from heat-treated, medium-carbon alloy steel with a yellow zinc chromate coating, designed for heavy-duty and high-stress applications.

Hex cap screws have a flat bearing surface, a hexagonal head, and a partially or fully threaded shank. Their six-sided head allows for easy tightening with standard wrenches and sockets, making them the preferred choice for demanding structural and mechanical assemblies.

Available sizes: 1/4″, 5/16″, 3/8″, 7/16″, 1/2″, 9/16″, 5/8″, 3/4″, 7/8″, and 1″.
