7" Curved Jaw Locking Pliers

Palmgren locking pliers are designed for repeatable gripping force across fabrication, repair, maintenance, and assembly operations. The hardened steel construction provides durability under repeated shop use while the adjustable locking mechanism allows controlled pressure across varying material types and thicknesses.

The Palmgren 70750 7" Curved Jaw Locking Pliers are the workhorse of the locking plier family. At 7 inches, they strike the right balance between the compact size of smaller models and the extended leverage of 10-inch pliers, making them the right tool for the widest variety of everyday professional tasks.

The adjustable lead screw design with 1/4" hex key drive allows operators to fine-tune jaw pressure for improved control during gripping, turning, clamping, and holding operations. Once adjusted, the locking mechanism maintains secure contact throughout demanding tasks.

Manufactured with hardened steel components for long service life, these locking pliers are engineered to withstand repeated use in fabrication, automotive, maintenance, and general shop applications. Large diameter rivets provide secure joints delivering durable and robust pliers.

Jaw geometry is designed to improve contact across flat, curved, and irregular surfaces while maintaining controlled gripping pressure. This helps reduce slipping during high-torque operations.

7-Inch Balanced Form Factor
The 7-inch length provides comfortable handling for a full range of professional tasks — from gripping pipe fittings to holding components during assembly — without the bulk of larger pliers or the limited leverage of compact models.

Curved Jaw for Maximum Contact
The curved jaw profile wraps around round stock, pipe, and irregular-shaped workpieces for maximum surface contact, improving grip security and reducing slip under load.

Precision Screw Adjustment
Set your desired jaw opening quickly with the screw mechanism. The adjustment holds precisely, so you get consistent clamping from use to use without needing to re-set constantly.

Integrated Wire Cutter
The built-in wire cutter adds convenience for cutting wire and small cable directly with the pliers, reducing the number of tools needed on the job.

Hardened Steel Jaws
The hardened steel jaws resist wear and maintain their gripping edge through extended professional use.

Q: When would I choose the 7" over the 5" or 10" models?
A: The 7" offers a middle ground: more reach than the 5" model, better maneuverability than the 10". Choose based on your typical workpiece size and space constraints.

Q: What's the maximum jaw opening on the 7" model?
A: The maximum jaw opening is 1-3/4 inches, accommodating workpieces up to 7 inches between the jaws.

Q: Is the 7" suitable for plumbing work?
A: Yes. The curved jaw design and mid-size length make it ideal for turning pipe fittings, holding tubing, and working in tight plumbing installations.

Q: Can I use this for welding fixture work?
A: Yes. Many fabricators use curved jaw locking pliers for temporary fixture work. The 7" length offers good maneuverability around workpieces.

Q: How is pressure applied with the screw-adjust mechanism?
A: Turn the lead screw to adjust the jaw opening. As you close the jaws, the lead screw creates clamping force. Continue turning until the workpiece is held securely.
