Well made and a good fit.
I needed a 22mm deep socket to change the oil pressure switch on a 2012 Toyota Corolla 1.8L. This socket was a close fit ( not sloppy ) and worked perfectly. I added a small block of foam inside to stop the switch from sliding all the wayinto the socket during installation, but there was so much room around the mounting boss it was easy to just threadthe switch in by hand and then tighten it with the socket and 1/2 inch ratchet from underneath the car.

Super high quality!
Perfect! A high-quality item from Tecton. I've bought many items from Tecton and they all have been head and shoulders above Craftsman. You can't go wrong with this brand.
