Replacement Grooved Jaws for Bench Vises

These nylon jaws replace the original faces on compatible PanaVise bench vises. They suit technicians and hobbyists who need a non-marring grip on delicate workpieces. The grooved surface helps hold small tubes, rods and circuit boards securely. Two mounting screws are included for installation.

Nylon Construction Limits Heat and Solvent Exposure

The material provides excellent electrical insulation for circuit-board work. It is not suited for high-temperature applications or prolonged contact with aggressive solvents that can degrade nylon. Metal jaw faces remain the choice for heavy clamping force or hot components. Users should verify chemical compatibility for their specific processes.

Upgrades Standard Metal Jaws on Models 301, 303.

The swap is worthwhile when the workpiece must not be marked or when electrical insulation is required. It does not increase the vise’s clamping capacity or opening width. Buyers who need wider jaws, deeper throats or higher torque should select a larger vise frame instead.

Questions about this item

Which PanaVise models do the 344 replacement jaws fit?

They are made for the 301, 303, 304 and 381 bench vises and include the two mounting screws.

What does the grooved nylon surface do for circuit boards and small tubes?

The grooves grip round stock without marring it while the nylon provides electrical insulation during soldering or testing.

What bench-vise interface do these jaws use and what does it limit?

They bolt onto the standard jaw faces of the listed PanaVise models, so they only work with those specific vise bodies.
