Hex Cap Screws Grade 5 Zinc - 9/16"-12 x 2-3/4" PT - Qty-25$$Hardware

A hex cap screw is a cap screw with a hexagonal head, designed to be driven by a wrench. An ASME B18.2.1 compliant cap screw has somewhat tighter tolerances than a hex bolt for the head. Hex cap screws are fully threaded in shorter lengths (usually around up to 1-1/4 inch, depending upon the bolt diameter), and partially threaded with a shoulder beneath the fastener hex head in longer lengths. Grade 5 Zinc plated steel hex cap screws have a layer of corrosion resistance Grade 5 Zinc hex cap screws are distinguished by three hash marks on top of the bolt's head
