20pc 7/16-20 Spline Extended Thread Lug Nuts With Key – Chrome, For Chevy GM

Here’s a set of 20 spline drive lug nuts with a 7/16-20 thread pitch.

They’re extended thread, chrome finished, and come with a matching key and socket.

The seat is a 60-degree conical/tapered style, so they fit a lot of classic GM cars—Chevy, Pontiac, Buick, Oldsmobile.

They’re about 1.65 inches tall, made from forged steel, and the socket size works with 3/4\, 13/16\, 19mm, and 21mm tools.

The set includes the key, nuts, and a spline socket.

Good for vintage cars or anyone wanting a clean, locking setup.
