The 510 uses the same basic "engine"
design as the 500, but has a largerdiameter
cylinder and piston. Both
tools require special fasteners made
with 60 carbon steel that is heat treated
to Rockwell C52. With these nails, both
PanelFast systems meet ICBO code recommendations.
Test results provided
by the manufacturer suggest that negative
wind shear holding strengths provided
by the 510 nailer are virtually the
same as screws.
These PanelFast nailers hold a 250-
nail coil. The magazine can hold either
11/2- or 2-inch nails. ET&F's nails are
treated with a corrosion-resistant coating
called AeroFast 1000, which withstands
1,000 hours of salt spray. This
provides ten times the corrosion resistance
of conventional zinc electroplated
fasteners. Manufacturer tests also
