The Engineer PZ-59 Neji-Saurus RX is an essential tool for mechanics, contractors, and DIY enthusiasts who frequently encounter stripped, rusted, or seized fasteners. Its primary benefit is the ability to remove damaged screws without the need for destructive drilling or complex extractor sets, relying instead on patented serrated jaw geometry to secure a firm grip. While these pliers offer exceptional torque and versatility for various bolt head types, users should note that they require sufficient physical hand strength to maintain the necessary pressure on extremely seized or corroded fasteners.

If there is any portion of the screw head protruding above the surface, the PZ-59 can grip it. If the screw is completely recessed below the surface, this tool will not be effective.
Because the serrations are aggressive to ensure a grip on damaged fasteners, they will leave marks on the metal surface of the screw or bolt.
The PZ-59 is designed for screws with head diameters ranging from approximately 3mm to 15mm.
No, the handles on the PZ-59 are not VDE rated or insulated for high-voltage electrical work. Do not use on live circuits.
The wire cutter is factory-hardened and integrated into the frame. It is not recommended to sharpen it manually as this may affect the structural integrity of the jaw alignment.
Ensure the fastener is not covered in heavy grease or oil; wipe the screw head and the plier jaws clean before attempting to grip.
Apply a small amount of penetrating lubricant to the pivot point and work the handles back and forth to distribute the oil.
The PZ-59 requires no special assembly. To ensure longevity, keep the hinge mechanism clean of metal shavings and debris. After using the pliers on rusted or corrosive materials, wipe the jaws with a light machine oil to prevent oxidation. While the steel is hardened for heavy-duty tasks, avoid using the pliers as a hammer, as extreme impact can compromise the alignment of the precision-engineered jaw serrations. Always store the tool in a dry, low-humidity environment when not in use.
