The small size of a bolt depends on the head diameter, or inner diameter. The smaller it is, the more torque you can put through that particular bolt before it fails and/or breaks. Typically bolts are made from carbon steel (0.0625 inch in diameter), stainless steel (0.125 inch in diameter) and titanium alloy metals ().

The “standard bolt sizes chart” is a list of common bolt sizes. The most common are listed first, the least common last.
