Product description
Heavy Hex Nuts, also called structural nuts, are both thicker and
wider than a standard (finished) hex nut and compatible with high
strength and large diameter bolts. Nuts in sizes 7/16" and smaller
are double chamfered. Nuts larger than 7/16" are either double
chamfered or chamfered on top with a washer faced bearing surface.
They are most commonly used in construction and engineering
applications and paired with heavy hex (structural) bolts.
s - size of the hexagon
e - the diameter of the circumscribed circle (not less than)
m - height of the nut
d - the nominal diameter of the thread
dw - contact surface diameter
