- Q.Are all zinc-coated nails
for pneumatic nailers created equal?
A.There are several
types of zinc-coated fasteners and they are
definitely not all equal. At the low-end of the
quality scale are electrogalvanized fasteners. On
these, a thin layer of zinc is electroplated onto
the fastener. This offers only minimal resistance
to corrosion. Collated fasteners for power drivers
are typically coated this way.
On the other end are hot-dipped fasteners, which
offer better resistance to corrosion. The nail may
be dipped once or twice. The double-dipped variety,
of course, has a much thicker coating that lasts
longer. At least one major manufacturer, the W. H.
Maze Company (Peru, IL 61354; 815/223-8290),
promises collated double-dipped nails for use in
nail guns within a year.
