Marson SST-2 Air Rivet Nut Tool (M39802)
The Marson SST-2 Air Rivet Nut Tool (M39802) is a pneumatic spin/spin production tool designed for fast, repetitive installation of rivet nuts in manufacturing, automotive, and industrial assembly environments. Operating at up to 1,500 RPM, the tool uses compressed air to apply consistent rotational force during each fastening cycle. Its stroke-free design simplifies setup and helps reduce installation variation, while the lightweight, balanced body supports prolonged use in high-volume production settings. The quick-change front-end assembly also allows the tool to accommodate compatible 10-24, 10-32, and 5mm threaded inserts.
Key Features and Benefits:
Spin/Spin Technology: Uses pneumatic rotation to install and release rivet nuts with consistent setting pressure.
High-Speed Performance: Operates at up to 1,500 RPM to reduce fastening time during repetitive production work.
No Stroke Adjustment Required: Simplifies tool setup and helps reduce installation errors caused by incorrect stroke settings.
Lightweight Ergonomic Design: The 3.2-pound body helps minimize operator fatigue during extended use.
Quick-Change Front-End Assembly: Allows compatible mandrels, anvils, and nose components to be changed efficiently.
Consistent Fastener Installation: Regulated pneumatic power supports uniform rivet nut compression across repeated cycles.

Package Contents: One Marson SST-2 pneumatic tool and two selected front-end assemblies
Disconnect the Air Supply: Keep the tool disconnected while inspecting or changing the front-end components.
Check the Mandrel Length: Confirm that the socket head cap screw extends beyond the anvil far enough for at least one full thread to protrude past the rivet nut.
Select the Front-End Assembly: Install the mandrel, anvil, and nose components that match the rivet nut thread size.
Connect the Air Supply: Attach the tool to a clean, dry, and regulated compressed air source using a suitable filter, regulator, and lubricator system.
Set the Air Pressure: Adjust the pressure between 45 and 100 PSI according to the insert material, thread size, and workpiece thickness.
Load the Rivet Nut: Engage the threaded insert onto the exposed mandrel until it is properly positioned against the anvil.
Position the Insert: Place the rivet nut completely into the correctly sized, pre-drilled hole in the workpiece.
Set the Fastener: Press the trigger to activate the spin/spin mechanism and collapse the insert securely against the reverse side of the material.
Release the Tool: Allow the reverse cycle to unthread the mandrel from the installed rivet nut.
Inspect the Installation: Confirm that the insert is firmly seated, properly aligned, and unable to rotate within the hole.
Benefits of Using Marson SST-2 Air Rivet Nut Tool (M39802):
Standardizes Production Results: Pneumatic operation helps maintain consistent rivet nut installation across high-volume assembly work.
Increases Work Output: The 1,500-RPM motor completes fastening cycles faster than manual installation tools.
Reduces Operator Effort: Air-powered operation eliminates the repetitive squeezing required by hand-operated rivet nut setters.
Limits Setup Errors: Stroke-free operation reduces the need for manual calibration between installations.
Minimizes Changeover Downtime: Replaceable front-end assemblies allow the tool to adapt to different compatible thread sizes.
Supports Continuous Production: Industrial pneumatic construction is suitable for repetitive duty cycles in demanding environments.
High-Torque Pneumatic Motor: Provides controlled rotational force for consistent insert setting.
Balanced Tool Housing: Centered weight distribution improves handling and alignment during repetitive operation.
Low-Vibration Configuration: Designed to provide smoother operation during continuous installation cycles.
Multi-Thread Capability: Supports compatible imperial and metric rivet nuts within the specified size range.
Industrial Air-System Compatibility: Operates with regulated compressed air commonly used in production facilities.
Replaceable Mandrel Hardware: Standard socket head cap screw design simplifies servicing and replacement.
Production-Oriented Construction: Built for frequent use in automotive, manufacturing, and industrial assembly applications.
