10" Straight 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 a job demands both the flat, even grip of a straight jaw and the high leverage of a full 10-inch tool, the Palmgren 71000 is the answer. This is the largest straight jaw locking plier in the Palmgren lineup, delivering maximum clamping force on flat stock, square sections, flanges, and parallel surfaces in automotive, fabrication, and industrial applications.

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

10-Inch Length for Maximum Leverage
The 10-inch overall length gives you the mechanical advantage needed for high-torque tasks: breaking loose stuck flat-sided fasteners, holding heavy stock during welding, and gripping large flat components that smaller pliers cannot manage effectively.

Straight Jaw for Flat Surface Grip
The straight jaw contacts flat surfaces across the full jaw width, delivering even clamping pressure that eliminates the stress concentration points created by curved jaws on flat stock. This protects workpiece surfaces and provides a more stable grip.

Precision Screw Jaw Adjustment
The screw adjustment lets you set the exact jaw opening required for your workpiece. Once set, the adjustment holds consistently from use to use, reducing setup time on repetitive heavy tasks.

Locking Mechanism
The powerful locking mechanism holds the jaws firmly at the set opening, providing hands-free clamping force that withstands the stress of heavy welding, grinding, and assembly work.

Integrated Wire Cutter
A built-in wire cutter adds versatility for cutting wire and cable without reaching for a separate tool.

Hardened Steel Construction
The 71000 is built from hardened steel throughout, handling the mechanical stress, heat exposure, and abrasion of demanding professional environments.

• Heavy flat stock and bar work in fabrication
• Automotive frame and body panel clamping
• Industrial maintenance and heavy equipment repair
• Structural steel assembly and welding
• Gripping large flat-sided fasteners and flanges
• Fabrication and welding support
• Automotive repair and maintenance
• Equipment service operations
• Gripping and turning irregular materials
• Assembly and positioning work

The 70700 7-inch straight jaw is the right choice for most everyday tasks. When you need additional leverage for heavy-duty work or when the workpiece is simply too large for a 7-inch tool, the 71000 provides the extra reach and mechanical advantage that heavy professional applications demand.

Q: When should I use straight jaw instead of curved jaw pliers?
A: Use straight jaw pliers for flat surfaces, sheet metal, and parallel workpieces. Curved jaws are better for round pipe and irregular shapes.

Q: Can I use straight jaw pliers for metalworking?
A: Yes. The parallel jaw contact and controlled pressure adjustment make straight jaw pliers excellent for sheet metal forming, bending, and assembly work.

Q: Is the jaw pressure adjustable?
A: Yes. The screw-adjust mechanism allows precise pressure control. Set it once for consistent results across multiple parts.

Q: What's the maximum jaw opening?
A: The 10" plier has a maximum jaw opening of 1-3/4 inches, suitable for parts up to 10 inches between the jaws.

Q: Does the plier prevent surface marring on finished materials?
A: The hardened steel jaws are designed for grip strength. For surface-sensitive work, consider adding protective pads or using the Palmgren Locking C-Clamp with Pads.
