Nejisaurus Z is designed for removing damaged, rusted, or stuck screws in tight spaces that cannot be reached with conventional pliers. The slim needle-nose head is enhanced with the patented vertically aligned jaws that grip even very small, flat screw heads in confined spaces. The patented side teeth intermesh each other so it firmly holds any thin material from 0.1 mm thickness. A T-shape melted grip helps the elastomer cover to keep its shape for long-lasting use while fitting comfortably in your hand. This allows you to work with low turning force, avoiding any injury. Suitable for your private DIY use or professional working environment.
