Hex Bolt Dimensions & Hex Cap Screw Dimension Chart

Hex Bolt Dimensions & Hex Cap Screw Dimensions

Have you ever wondered “how thick is the head of the bolt that I just bought”?  Well, good news is that fasteners are made to universal specifications that are known globally.  Therefore, all you have to do is look at a hex bolt dimensions chart and you will find everything you need to know.  And regardless if you are looking for a grade 5 hex cap screw or a grade 8 hex cap screw, their dimensional measurements will be identical.  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!

Lightning Bolt has many people that contact us which interchange the names of hex cap screws and hex bolts as they are synonymous… they are not.

Hex bolts are “less precise” and therefore cheaper than hex cap screws.  Additional features that hex cap screws have which make them superior is that they are manufactured with a higher level of preclusion (tighter tolerance) and also possess a washer facing under the head of the bolt.   Standard Hex cap screw dimensions include:
