Adjustable Tongue-and-Groove Pliers Rockforce 12" (300 mm) RF-613G300

Adjustable tongue-and-groove pliers Rockforce 12" (300 mm) RF-613G300 are steel construction pliers designed for gripping and turning pipes, fittings and fasteners across a range of jaw openings. The tool features a multi-position tongue-and-groove adjustment that allows secure clamping on different diameters and flat surfaces, providing a stable hold for general mechanical, plumbing and maintenance tasks in workshops and homes.

Advantages

Made from durable steel, these pliers offer reliable strength and wear resistance for repeated use. The tongue-and-groove mechanism provides quick, positive adjustment to multiple positions, ensuring an even grip and reducing slippage on round or hex-shaped objects. The long handle gives mechanical advantage for higher torque with less effort, while the serrated jaws improve contact with smooth or threaded surfaces.

Suitable for

• Gripping and turning pipes and plumbing fittings
• Holding and loosening nuts, bolts and other fasteners
• General workshop maintenance and repair tasks
• Household DIY and installation work

Key specifications

• Overall length: 300 mm (12")
• Material: steel construction for strength and durability
• Adjustment type: tongue-and-groove with multiple locking positions
• Jaw type: serrated gripping surfaces for improved bite
• Handle: long handles for increased leverage

How to use

Select a jaw position by sliding the lower handle so the tongue engages the appropriate groove for the object size. Place the jaws over the workpiece, then squeeze the handles until the jaws close firmly around the part. Apply steady turning force while maintaining a secure grip; reposition the pliers and change groove settings as needed for different diameters. Release by easing pressure on the handles and sliding the tongue out of the groove to open the jaws.

Usage recommendations

Use the pliers within their intended mechanical limits and avoid using them as a hammer or pry bar. Keep jaws clean and free of oil for best grip, and inspect regularly for wear or deformation. For work on soft or finished surfaces, consider using protective jaw covers to prevent surface damage.
