Review on TE CO 31332L Knurled Swivel Thread by Jathan Louis

I have bought several types of Revain rotary thumbscrews, this one is better made. The finish is good, the tip is wear resistant, highly recommended for applications where you want to apply even pressure to the holding surface without scratching or damaging it. The swivel pad has reverse threads to insert the screw into the base. So if you tighten the screw clockwise, the pad will not loosen when not pulled but when pushed because the screw tip threads are only partial. Once it passes the pad's threads, it begins to spin freely. In other words, loosen: You pull the pad away from the screw by turning the screw clockwise. Fastening: You press the pad against the screw by turning the screw counterclockwise.
