Tristate has a wide selection of locknuts available, from grade C, on collar style & auto style. Our lock nuts are heat treated, hardened, and have a flat bearing face. Just let us know what you are looking for! Our flange locknuts, both grade F and Grade G are non-serrated. We carry a grade 9 hex nut and locknut which we call “T-9”. We also stock several sizes of thin collar locknuts and heavy hex (2-H) locknuts.

We apply the locking feature by squeezing the nuts from opposite sides in order to “ovalize”  the I.D.  Our patented machinery allows us to get very consistent torques.
