T-slot roll-in nuts are an essential component for building aluminium profile structures and without T-slot roll-in nuts these machine building systems would not be the success they are now. T-slot roll-in nuts are used for the majority of connection methods. Unlike the more common squared shaped t-slot nuts used for milling machine tables and other tooling applications,T-slot roll-in nuts have a semi-elliptical shape designed specifically for inserting with a reasonable fit into the t-slot grooves of the aluminium profile without having to slide them in from either side of the profile.
