5" 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.

When you need the holding power of locking pliers in a compact, lightweight form, the Palmgren 70550 5" Curved Jaw Locking Pliers are the answer. Designed for work in tight spaces and on small components, the 70550 delivers reliable gripping performance in situations where full-size pliers are impractical.

The adjustable lead screw design comes with a 1/4" hex key drive allowing 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 durability & 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.

5-Inch Compact Design

The 5-inch length is ideal for tight-clearance work, small assembly tasks, and situations where a larger tool is simply too cumbersome. Despite its compact size, the locking mechanism provides strong holding force.

Curved Jaw for Round and Irregular Shapes

The curved jaw profile provides excellent contact on round stock, small pipe, and irregularly shaped fasteners. The curvature conforms to the workpiece, maximizing grip area and reducing slip.

Precision Screw Adjustment

Fine-tune the jaw opening with the screw adjustment mechanism. Set the opening once for repetitive tasks or adjust on the fly for varied workpiece sizes.

Locking Mechanism

The locking jaw holds your set opening, allowing hands-free clamping. This frees your other hand for guiding, measuring, or performing secondary operations.

Hardened Steel Jaws

Despite its smaller size, the 70550 features hardened steel jaws that retain their sharp edge through repeated use.

Q: Are the 5" pliers suitable for electronics work?
A: Yes. The compact size and controlled clamping pressure make them ideal for electronics assembly, jewelry fabrication, and fine detail work.

Q: What's the maximum jaw opening on the 5" model?
A: The maximum jaw opening is 1-1/4 inches, accommodating small parts up to 5 inches between the jaws.

Q: Can I use the 5" curved jaw for automotive work?
A: Yes, particularly for small fasteners, fuel line fittings, and detail work in tight engine compartments.

Q: How does the 5" compare to the 6" model?
A: The 5" is slightly more compact for confined spaces; the 6" offers a bit more capacity. Both feature curved jaws for round stock.

Q: Is pressure adjustment needed for delicate workpieces?
A: Yes. The screw-adjust mechanism lets you apply just the right pressure for small, delicate parts without over-clamping.
