This is the newest version of my wheel check indicator installer tool.   what's different you ask?  to start with its thicker and then it has a much deeper and a little bigger center hole to allow larger wheel studs to fit in it.
This is a simple tool to push the wheel nut indicators on.  Simply set the wheel nut indicator in the tool and push it onto the nut. 
make sure to check out the new removal tool also!

CLIMATE NOTE: This is printed in PLA plastic which is known to warp in higher temperatures or become brittle when exposed to UV light. If your car is in a hot climate and in the sun, the high temperatures (>125℉) and direct sunlight could warp this adapter or cause it to break. This particularly applies to places like Phoenix, Southern California, etc. where temperatures regularly reach into the 100℉. An average "hot" summer day in Minnesota, or Wisconsin, or New York could also warp these if your car sits in the sun! 
This product is 3D printed. Due to the nature of 3D printing, there may be a seam, layer lines, and/or small imperfections.
Washing instructions: Hand wash only with cool, soapy water. Rinse and dry.
