Have you ever been stuck with rusty, stripped, damaged, jammed or tamper-proof screws and needed to remove that screw? The PZ-32 js Neji-saurus can do the job with remarkable ease. At first glance, these pliers look just like normal pliers, however these pliers have a unique a twist. These pliers have a patented design of vertical and horizontal serrated inside jaws which bite into screw heads of various shapes without slipping (ordinary pliers will simply slip or slip off when try to twist a screw out - these pliers won't). Much easier to use versus other screw extractor products. Additionally, the jaws on these versatile pliers also have inter-meshed teeth which allows a firm grip – even on the most thinnest of materials (shim etc.). A black oxide coating enhances rust resistance.
