Grade 8 Yellow Zinc Fine Thread hex cap screw

A Grade 8 Yellow Zinc Fine Thread Hex Cap Screw is a high-strength fastener made from heat-treated, medium-carbon alloy steel with a yellow zinc chromate coating and a finer thread pitch, offering superior holding power in metal-to-metal applications.

Hex cap screws have a flat bearing surface, a hexagonal head, and a partially or fully threaded shank. Their six-sided head allows easy tightening with standard wrenches and sockets, and the fine thread pitch provides greater tensile strength and more precise torque control than coarse-thread equivalents.

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