Review on Dsycar 12 Pack Tire Stem Valve Caps Black, Thin Blue Line American Flag Hexagon Shape Design, Premium Metal Aluminum Rubber Seal Tire Valve Stem Caps ,Universal Fit (Mini - Black Blue USA) by Jonah Riggle

Do not buy these or any other metal valve caps because they will corrode, and you won't be able to get them off. I used a vice grip on the stem and a 10mm socket on the cap and still couldn't get any of the 4 to budge. I ended up having to use a hacksaw to cut them off because they all corroded (the white stuff on the inside threads in the pictures). Luckily this wasn't an emergency so I had the time and tools to remove them. Save yourself the headache, please.
