=5. Wire Nails.=—The term =wire nail= is applied to nails made from
drawn wire, or wire rods. Since their introduction some years ago, wire
nails have become decidedly popular, and in some localities are used in
preference to the old-style cut nails, owing to the fact that there are
a greater number to the pound, which makes them cheaper than cut nails
at the same price per keg. The size and number of common wire nails to
the pound are given in Table III. By comparing the columns in Tables II
and III giving the number of nails to the pound for both cut and wire
nails, it can be readily seen that the wire nails are greater in number
for a given weight than cut nails of the same size. For this reason,
the wire nails are used by contractors on cheap work.
Wire nails are more liable to rust than cut or wrought nails, and are
consequently not so durable in damp situations; they also have less
holding power and more must be used to obtain the same strength.
