The Knipex 86 03 250 SB Pliers Wrench is a 250 mm adjustable pliers designed to combine the gripping capability of an adjustable spanner with the secure hold of parallel pliers. Its primary use is to grip, hold and tighten hex nuts, fittings and flat workpieces without damaging surfaces, making it ideal for assembly, maintenance and commissioning tasks where a non-marring and positive grip is required.

Manufactured from chrome vanadium (CrV) steel and oil-hardened for durability, the Pliers Wrench features precision-machined, flat parallel jaws that close evenly to distribute clamping force across the workpiece. The tool has a polished, chrome-plated finish for corrosion resistance and easy cleaning, and ergonomically dipped handles for improved grip and comfort during extended use. As a hand tool it is produced to meet Knipex’s exacting quality requirements and conforms with the relevant DIN/ISO/BS standards that apply to precision pliers and adjustable wrenches for professional applications.

The head and jaw design eliminate the slip typically associated with traditional adjustable wrenches: the parallel action reduces marking on nuts and fittings and provides a firm hold on round, hexagonal and flat materials. There is no drive type or thread to specify on this tool; adjustment is rapid and stable via the integrated adjustment groove and resilient joint. The slim joint profile gives access in confined spaces where a conventional adjustable spanner would not fit.

Typical industries and applications include plumbing and heating, HVAC, electrical installation, automotive repair, mechanical assembly and general maintenance. It is particularly useful where workpieces have plated or soft finishes that must not be damaged, and for repetitive tightening tasks where a consistent grip reduces operator fatigue and slip-related rework.

Key benefits include long-term corrosion protection from the chrome finish, high strength from the hardened CrV steel and broad compatibility with common nut and fitting sizes thanks to the parallel-jaw geometry.
