Slip-joint pliers for trade and DIY
The WORKPRO W031489 is an 8.5-inch slip-joint plier built from high-carbon steel hardened to HRC 58–60. A black oxide finish with transparent electrophoretic coating resists rust. Thermoplastic rubber handles give a non-slip grip for technicians and home users needing a durable, general-purpose gripping tool.
Box-joint limits and jaw travel
The box-joint design reduces wobble and keeps jaws aligned better than lap-joint types. Four fixed jaw positions are selected by a quick-adjust button. Side jaws open from 0.160.75 inch; front jaws open from 0.090.71 inch. Only one adjustment position is available at a time, so very fine increments between settings are not possible.
Capacity and headroom
Diamond-grip jaws and nail-pulling teeth hold pipe and fasteners up to the rated 8.5-inch pipe capacity. The hardened steel and box joint handle high torque without flex. The tool runs out of reach when workpieces exceed the maximum jaw spread or when access demands a longer handle than the 24.003-centimetre overall length provides.

Questions about this item
Should I choose the 8.5 inch model or the 9.5 inch wire crimper for general plumbing tasks?
The 8.5 inch slip joint pliers offer a pipe capacity of 8.5 inches and four adjustable jaw positions, making them versatile for gripping various pipe sizes. The 9.5 inch tool is a dedicated wire crimper, not a general-purpose plier.
What does the 8.5 inch pipe capacity mean when I am actually using the pliers?
It means the jaws can open wide enough to grip pipes or fittings up to 8.5 inches in diameter. The side jaw opening ranges from .160.75 inch and the front jaw from .090.71 inch, covering a broad range of workpiece sizes.
How does the box-joint design affect the tool's performance compared to standard lap-joint pliers?
The box-joint structure provides greater strength, reduces jaw wobble, and improves alignment. This ensures smoother operation and long-lasting durability during heavy-duty use.
