Product Description
- 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.
 - In general, fine thread fasteners are about 10% stronger than coarse threads under static loading.
