GaoYi will meet all your needs for customization of heavy hex nuts. These nuts are wider and thicker than a standard hex nut, and often used with large diameter, high strength hex bolts or hex screws. Heavy hex nuts are often used in metal instruments, as well as environments where gas or oil is prevalent. These nuts feature a longer thread connection area, higher stretching capacity, and a broader resistance. Coating materials include zinc, black zinc and hot-dip galvanizing.

GaoYi provides heavy hex nuts with a standard size from 1/4 inch to 4 inches.
