1/2"-13 Finished Hex Nuts 18.8 Stainless Steel 100 - Box
Hex nuts (also referred to as finished nuts) are compatible with low carbon
steel bolts such as Grade 2 ASTM A307. Grade 5 and Grade 8 nuts are also
available in a finished pattern. Since hot dip galvanizing typically adds 2.2
to 5 mils of thickness to the threaded portion of a fastener, galvanized hex
nuts are tapped oversize to compensate for the corrosion resistant coating on
Stainless steel is used extensively throughout industry for both original
equipment manufacture as well as for replacement. Incases where a joint is
designed to be taken apart and reassembled, the corrosion resistance of the
fastener is particularly important so that corrosion will in no way hamper or
prevent its removal. The cost of removing rusty bolts, and replacing them with
new ones, is more expensive than using corrosion resistant fasteners to begin
with. Additionally, many designers consider the extra coat of stainless steel
fasteners as inexpensive insurance against possible failure or loss of
The austenitic (300 series) stainless steels are characterized as having
excellent corrosion resistance. Chromium is the element that provides the
stainless steel with its "stainless" name. These specifications cover the 300
series stainless steels, all of which are essentially 18-8 (18% chromium and 8%
nickel) materials, with compositions very close to the nominal composition for
Type 304. If an application calls for a material with corrosion resistant
properties better than that of Type 304, Type 316 is the next logical
candidate. Type 316 stainless steel is a higher alloyed material containing
2-3% molybdenum, which provides pitting and crevice corrosion-resistant
properties, especially in environments containing chlorides.
