5.6 grade Railway Square Head Bolt & Screw With Plain or HDG
treatment
Square Head Bolts offer a large bearing area for positive gripping
with an open or adjustable wrench which means less slippage. Head
width or wrench size is measured across the flats. Length is
measured from under the head.

A hex cap screw is a cap screw with a hexagonal head, designed to
be driven by a wrench (spanner). An ASME B18.2.1 compliant cap
screw has somewhat tighter tolerances than a hex bolt for the head
height and the shank length. The nature of the tolerance difference
allows an ASME B18.2.1 hex cap screw to always fit where a hex bolt
is installed, but a hex bolt could be slightly too large to be used
where a hex cap screw is designed in.
