Unior Adjustable Box Joint Pliers Tool for Nut Bolt and Bike Repair Service

Unior Adjustable Box Joint Pliers – 240mm Professional Grip Tool

The Unior Adjustable Box Joint Pliers are built for high-grip applications where extra holding power is needed. Designed for professional mechanics and workshop use, these pliers feature drop-forged chrome vanadium steel construction and a 7-position adjustable jaw capable of gripping objects up to 35mm in diameter.

Unlike parallel-jaw pliers, this design provides more aggressive gripping power, making it ideal for stubborn fasteners, rounded bolts, or cylindrical components such as stuck seatposts. The adjustable box-joint mechanism allows quick repositioning of the jaws while maintaining secure engagement.

The ergonomic handle design also helps prevent fingers from being pinched between the handles, improving safety and comfort during heavy-duty work.
