Hex cap screws are manufactured to tighter tolerances as compared to hex bolts.

The heads of grade 5 steel fasteners are typically marked with 3 raised radial lines.

The washer face under the head provides a precision bearing surface.

Grade 5 steel fasteners have a minimum tensile strength of 105,000 pounds per square inch.

The chamfered point improves engagement with a nut or pre-tapped hole.
