Marson Heavy Duty Rivet Nut Thread Setter (34604) (Model M34604)
The Marson Heavy Duty Rivet Nut Thread Setter (34604) is a professional-grade manual tool designed for installing threaded inserts in thin-gauge sheet metal, aluminum, steel, and other materials where conventional tapping or welding may be impractical. Its lever-action mechanism pulls the rivet nut against the reverse side of a pre-drilled hole, causing the insert body to expand and form a secure, load-bearing female thread. Suitable for automotive assembly, vehicle maintenance, fabrication, and industrial manufacturing, the tool supports a broad range of imperial and metric insert sizes while providing controlled, repeatable fastening performance.
Key Features and Benefits:
Broad Installation Range: Supports imperial threaded inserts from #10-24 and #10-32 through 3/8-16, as well as metric sizes from M5 through M10.
Adjustable Stroke Mechanism: Allows the setting distance to be configured according to the insert size and material thickness.
Easy-Turn Release System: Helps unthread the mandrel from the installed rivet nut while reducing the risk of binding or seizure.
Heavy-Duty Construction: Combines a forged, heat-treated steel upper handle with a precision die-cast aluminum alloy body.
Quick-Change Tooling: Interchangeable mandrels and nosepieces support efficient transitions between compatible insert sizes.
High-Leverage Operation: Multi-point lever action increases force output for installing larger threaded inserts manually.

Select the Tooling: Choose the mandrel and nosepiece that match the thread size of the rivet nut being installed.
Configure the Tool: Install and securely tighten the selected mandrel and nosepiece.
Prepare the Mounting Hole: Drill a correctly sized hole in the workpiece and remove any burrs, dirt, or debris.
Adjust the Stroke: Set the installation stroke according to the insert dimensions and thickness of the base material.
Load the Rivet Nut: Thread the insert onto the mandrel until its flange rests firmly against the nosepiece.
Position the Insert: Place the rivet nut completely into the prepared hole with its flange seated against the workpiece.
Set the Fastener: Bring the handles together firmly to retract the mandrel and compress the insert against the reverse side of the material.
Check the Installation: Confirm that the insert is securely seated, properly aligned, and unable to rotate inside the hole.
Release the Tool: Use the Easy-Turn mechanism to unthread the mandrel from the installed rivet nut.
Attach the Component: Install the required component using a compatible bolt or machine screw.
Benefits of Using Marson Heavy Duty Rivet Nut Thread Setter (34604):
Creates Weld-Free Threads: Installs permanent threaded anchors without heat, sparks, welding equipment, or electrical power.
Protects Finished Surfaces: Mechanical installation helps avoid heat-related discoloration and damage to painted or coated materials.
Supports Blind-Side Assembly: Creates threaded mounting points when access to the reverse side of the workpiece is unavailable.
Handles Large Insert Sizes: Heavy-duty leverage supports imperial inserts up to 3/8-16 and metric inserts up to M10.
Improves Installation Consistency: Adjustable stroke control helps maintain uniform insert compression across repeated applications.
Reduces Setup Downtime: Replaceable installation components simplify changes between supported thread sizes.
Multi-Point Lever Geometry: Multiplies manual input force for controlled installation of larger threaded inserts.
Textured Handle Grips: Provide a secure gripping surface and help reduce hand slippage during operation.
Lightweight Structural Body: Aluminum alloy construction limits tool weight while maintaining rigidity.
Reinforced Steel Handle: Heat-treated upper handle withstands the stress generated during high-force setting cycles.
Extended-Reach Profile: Provides additional clearance for recessed or obstructed installation locations.
Mandrel Release Assistance: Integrated reverse mechanism simplifies removal of the tool after the insert is set.
Expandable Size Compatibility: Accepts additional compatible mandrels and nosepieces for varied project requirements.
