Hex Head Cap Screws
Hex head cap screws come in a variety of sizes, finishes, grades and threads. The most popular hex cap screws are the grade 5 steel bolts with a zinc finish. When looking for outdoor use or a stronger bolt the grade 8 yellow zinc plated bolts are a better choice. The name hex cap screw and hex bolt are commonly interchanged. A hex cap screw is actually manufactured with tighter tolerances and can be used anywhere a hex bolt is used. A common feature on a hex cap screw is a washer surface directly under the head which creates a better seal.

Hex Head
Bolts or cap screws with a hex head have a hexagonal or six sided head. These bolts can be screwed in with a common wrench or socket drive. They are better than a square head bolt when in tight places. The hex head can be driven with shorter wrench swings because of the six sided head.

Bolt Grades
What do the varous grades of hex bolts refer to like grade2, grade 5 and grade8? Information on various bolt head markings and grades can be found here: Bolt Grades and Head Markings
