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
