Nuts
Heavy
Hex Nuts:
Heavy
hex nuts are used when more "beef" is
needed than in standard hex nuts. Often heavy
hex nuts are used in high temperature and high
pressure applications, particularly those involving
flanged joints. Generally the width across the
flats is 1/8 of an inch larger than common hex
nuts. The thickness of heavy hex nuts is equal
to approximately the nominal diameter, which is
about 10% thicker than a regular hex nut.
ASTM
(ASME) A194 is one specification that is often
sited in connection with heavy hex nuts. Several
different materials are covered by ASTM A194.
Nickel Systems can supply heavy hex nuts conforming
to: ASTM A194 2H (1045 Steel, Heat-Treated), ASTM
A194 Grade 6 (410 Stainless), ASTM A194 Grade
8 (304 Stainless), ASTM A194 Grade 8C (347 Stainless),
ASTM A194 Grade 8M (316 Stainless), A194 Grade
8R (Nitronic® 50), A194 Grade 8S (Nitronic®
60), and A194 Grade 8T (321 Stainless).
Nickel
Systems is not limited to materials covered by
ASTM A194. We maintain heavy hex nut inventory
in Alloy C276 (Hastelloy® C), Alloy 20 (Carpenter
20®), and Duplex 2205. Metric sizes and other
alloys can be provided.
