Overview
The Pro Comp 26194 is a 20-piece chrome lug nut kit in 9/16 inch size with an 18 thread listed in the title. The spline style nuts come with four chrome valve stems and one lug socket.
Because this is a set of wheel lug nuts, the 9/16 x 18 size and spline style are what to check against your studs.

Stud and seat compatibility
Inch-size lug nuts are sized in fractions of an inch, and the thread pitch decides whether a nut seats cleanly on a stud. An 18 thread is a fine pitch, so a nut that looks similar may still cross thread if its pitch differs. Before fitting, run each nut down the stud by hand until it seats, then tighten. Hand-starting protects both the stud and the nut.
Chrome finishes look good when new but can scratch during installation or chip from road debris. Wipe the seats clean before mounting a wheel, because grit trapped under a spline seat can change how the nut tightens. If a chrome nut shows pitting or rounded spline edges, replace it rather than trusting it to hold the wheel.
