Review on Davies Thermoplastic Threaded Through Diameter by Tony Conlon

The pen itself is a good size and the price is right. But the threads weren't 1/4 by 20 like they should have been. They were close enough that I could run a tap through them to get them to 1/4 by 20. Also the description doesn't tell you but they have a nut with nylock inside which is counterproductive compared to loosening the handle and pulling again and again. Nylock nuts are for things that need to be tightened and left alone. Someone didn't know what they were doing to design it. My faucet also took care of the nylock nut.
