I bought this for the oil filter cap on my Jeep Wrangler JK (2013 - 3.6L Pentastar, 6 speed). The cap is plastic and has a specific torque value applied to it. (18 ft lbs) The plastic cap has a 24mm hex head formed into the top for removal. The filter snaps into this cap and the included rubber O ring must be replaced with each new filter. The only 24mm socket I have is for a 1/2" drive but my 1/2" torque wrench only goes down to like 50 ft lbs. This adapter will allow me to use my 3/8" torque wrench to prevent leakage as well as cracking due to over- or under-torquing the *very* expensive plastic cap or housing. Plating is smooth, without flaw, and the detent ball has a firm spring that still releases pretty easily. The plating on the inside of the female 3/" opening is a bit bright and unpolished, but it was inexpensive. Otherwise it is a solid chunk of metal that does its job as expected. I will look into more of these Williams Tools products. They are under the...
It's advanced features are amazing. It features a state of the art square hole that fits my 3/8s wrench and a 1/2 square protuberance with a ball pushed by a spring. I think that the square hole would make the mayans envious. I know it makes me wonder. I have never seen a square drill bit. Anyways. It did not break when I tightened M14 bolts at 220 pounds per foot torque.
This item works perfectly so that I can use my 1/2 sockets and extensions with my 3/8 ratchet, which is smaller and can be used in tighter places than my larger 1/2 inch ratchet.
