Stanley 84-389 9- 1/2" Long Nose Professional Locking Plier

Key specs include: length of 9-1/2 inches, forged and machined jaw for precision gripping, adjustable three‑piece design for versatility, ultra‑strong locking mechanism with a heat‑treated release, die‑cast handle with molded vinyl panels, cushioned non‑slip grips, and heavy‑duty steel construction for reliable performance.

The adjustable three‑piece jaw design lets you tailor the gripping width and angle to different shapes—whether you’re grabbing hex nuts, bolts, threaded rods, or irregular objects—helping you maintain secure, aligned holds in tight or awkward spaces.

A forged and machined jaw offers higher strength, durability, and precision compared to basic stamped jaws. This means better grip, reduced slippage, and longer tool life when handling tough fasteners or components.

You can clamp hex nuts, bolts, threaded rods, round bars, pipes, and other common fasteners. The sturdy jaws and locking mechanism help maintain a secure hold without constant re‑adjustment.

Position the jaws around the object, squeeze the handles to engage the lock, and adjust the clamping pressure as needed using the tool’s locking mechanism. To release, use the release lever. For different grip widths, reposition the jaws and re‑lock as necessary.

Keep fingers away from the jaws’ closing area, wear eye protection for tasks with metal shavings or debris, ensure the tool is clean and free of damage before use, avoid using the plier as a hammer or prying tool, and never exceed the tool’s intended grip capacity. Store after cleaning and drying to prevent corrosion.

Wipe clean after use, apply a light machine oil to the pivot and locking mechanism periodically, avoid exposure to moisture, and store in a dry place. Inspect jaws for wear or cracking and replace if damaged to maintain safe operation.
