Review on 🔧 Derale 14000 Magnetic Drain Plug Kit: Enhanced Performance, Black by Stephen Ball

Thread size 1/2-20 and a good flanged head that protects the oil pan from contact with the bushing. The magnet is twice the size of a previously ordered competitor product. The only downside is the cheap galvanizing instead of the more durable cadmium. Also, the threads are rough and stopped halfway through the perforating threads in my thick aluminum oil pan. I suppose I could have forced it, instead I chose to screw the derale connector with a 1/2-20 die. After that it fits perfectly and works great.
