Marson Mar39010 and Mar39035 Replacement Jaws (96013)
The Marson Mar39010 and Mar39035 Replacement Jaws (96013) are maintenance components designed for Marson Big Daddy and VHR-2 rivet tools. The internal jaws are responsible for gripping the rivet mandrel and pulling it through the nosepiece to set the fastener. Because these components are exposed to repeated friction and mechanical pressure, their gripping surfaces can gradually wear and become less effective.
Worn jaws may cause mandrel slippage, incomplete rivet installation, or the need for multiple pull cycles. Installing the Marson 96013 replacement jaws restores fresh gripping surfaces, allowing the tool to engage the mandrel more securely and complete rivet installations with greater consistency.
The replacement kit contains two matched jaws that work together inside the tool’s nose assembly. Both jaws should be replaced at the same time to maintain proper alignment, balanced pressure, and even wear. This allows operators to restore the performance of compatible Marson rivet tools without replacing the entire unit.
Regular inspection is recommended for rivet tools used frequently or in high-volume fastening environments. Increased operating effort, audible slipping, repeated pull cycles, or visible wear on the jaw teeth may indicate that replacement is necessary.
Key Features and Benefits:
Restores Tool Functionality: Replaces worn gripping components to help eliminate mandrel slippage during rivet installation.
Precise Compatibility: Designed specifically for Marson Big Daddy and VHR-2 rivet tools to support proper fitment.
Improved Mechanical Efficiency: Helps the jaws grip the mandrel securely for more consistent, single-cycle rivet setting.
Factory-Specified Maintenance: Provides a direct replacement solution for tools that have lost gripping performance.
Matched Two-Jaw Set: Includes two components designed to operate together for balanced pressure and correct alignment.
