ASME B1.12 Document Information:
Title
Class 5 Interference-Fit Thread
ASME International
Publication Date:
Jan 1, 1987
Scope:
This Standard provides dimensional tables for external and internal
plastic flow interference-fit
(Class 5) threads of modified National thread form in the coarse
thread series (NC) in sizes 0.250
in. through 1.500 in. This is not the ANSI B1.1 UN thread form. It is
intended that designs
conforming with this Standard will provide adequate torque conditions
which fall within the limits
shown in Table 8. The minimum torques are intended to be sufficient to
insure that externally
threaded members will not loosen in service; the maximum torques
establish a ceiling below which
seizing, galling, or torsional failure of the externally threaded
components is reduced. This
Standard provides for the maximum allowable interference.
Appendices A, B, C, and D contain useful information that is
supplementary to this Standard, such
as reprints of the obsolete tentative and alternate Class 5 standards,
U.S. Navy ship
specifications for elastic interference-fit coarse thread series from
0.250 in. through 2.000 in.,
U.S. Navy ship specifications for Class 5 Modified which includes
nickel-copper-aluminum alloy
external threads, and an interference metal comparison of standard to
nonstandard interference-fit
threads.
