Two black flange-head bolts compared side by side on a workbench…

Two black flange-head hex bolts laid side by side on a scratched brown workbench for comparison — the upper one longer with a shorter threaded section, the lower one shorter with threads running much further up the shank. A screwdriver with a red-and-black handle lies at the left edge; frame stamped 08/08/2009.
