Only the material that they are made from is different. However, make sure you are comparing apples to apples, because “Hex Bolts” and “Hex cap screws” are different!sp.info Hex Head Cap Screws McMaster-CarrTight-Spot Hex Head Screws. A high -strength alternative to blind rivets, these Class 8. 8 steel screws can be used when only one side of the material is accessible. When the screw is tightened, the attached nut expands the sleeve to create a strong clamping force on the back of the material.sp.info Grades of Bolts - The Home DepotThere are several grades of bolts but the three common grades for SAE are 2, 5 and 8. The common class (grades) for metric are 5.8, 8.8, 10.9 and 12.9. Each grade has a specific bolt strength. No matter the system used to grade the bolts, the higher the number means the stronger the bolt.
