Material and Design
Anti-Galling Properties
.
The HYTORC Gall-Free Nut offers anti-galling performance
in a standard hex nut geometry in all common hex sizes, and
can be customized for non-standard application constraints as
well. Its patent-pending design geometry and unique material
conditioning can eliminate galling even on fine high-alloy
threads operating at elevated loads and temperatures without
lubricant or anti-seize.
The Gall Free Nut is designed with a
pronounced feature on the “non” load
bearing side to help guide the installer
to ensure that the nut is installed
properly. The nut is installed with the
load bearing surface always oriented
towards the flange of the application.
The two-part design consists of interlocking inner and
outer sleeves with tapered threads that integrate
advanced anti-galling properties. Compatible with
standard bolt threads, the HYTORC Gall-Free
Nut can be finished in a variety of coatings and
materials to suit your specific applications
The new Gall Free Nut thread design eliminates
metal transfer that may occur in fasteners without
lubrication and increased friction over extended time
periods. This technology counters the galling effect
of plastic deformation and micro-scale material
transfer at the thread surfaces that occur during
assembly
