Hex Cap Screws

Hex cap screws have a thick hexagonal-shaped head cap and often feature a washer face under the head, which provides good bearing when tightened with a wrench. These screws are used in various applications that require threaded fastening with nuts that are also very corrosion resistant. Hex cap screws are available in different grades ranging from grade 2, which is made from low carbon steel, to grade 9, which is among the highest grade alloys.
