Marson SST-1 Air Rivet Nut Tool (M39801)

The Marson SST-1 Air Rivet Nut Tool (M39801) is a pneumatic spin/spin installation tool designed for rapidly setting small-diameter rivet nuts in automotive, industrial, manufacturing, and production environments. Operating at up to 3,000 RPM, the tool threads onto the insert, applies controlled setting force, and reverses off after installation. Its stroke-free design helps maintain consistent fastening pressure without requiring repeated manual adjustments. The lightweight, balanced housing and quick-change nosepiece assembly support efficient use during high-volume installation tasks.

Key Features and Benefits:

• Spin/Spin Technology: Uses pneumatic rotation to install and release threaded inserts without requiring manual stroke adjustment.
• High-Speed Operation: Reaches up to 3,000 RPM to reduce installation time during repetitive fastening work.
• Consistent Setting Pressure: Applies uniform installation force to help protect the insert and surrounding workpiece.
• Lightweight Ergonomic Design: Balanced 3.2-pound construction helps reduce operator fatigue during prolonged use.
• Quick-Change Tooling: Nosepiece and mandrel components can be exchanged efficiently when changing fastener sizes.
• Imperial and Metric Compatibility: Supports common threaded inserts ranging from #4-40 through #8-32, as well as M3 and M4.

How to Use:

• Prepare the Air Supply: Connect the tool to a clean, regulated compressed air source operating between 45 and 100 PSI.
• Select the Tooling: Choose the nosepiece and mandrel that match the thread size of the rivet nut being installed.
• Configure the Tool: Install the selected mandrel and nosepiece assembly and tighten all components securely.
• Prepare the Mounting Hole: Drill or verify a correctly sized hole in the workpiece and remove any burrs, dirt, or debris.
• Load the Rivet Nut: Thread the insert onto the exposed mandrel until its flange rests against the nosepiece.
• Position the Insert: Place the rivet nut completely into the prepared hole while keeping the tool aligned with the work surface.
• Set the Fastener: Press the trigger to activate the spin-in cycle and secure the rivet nut within the material.
• Check the Installation: Confirm that the insert is firmly seated, properly aligned, and unable to rotate inside the hole.
• Release the Tool: Activate the reverse function to spin the mandrel out of the installed rivet nut.
• Attach the Component: Install the required part using a compatible machine screw or bolt.

Benefits of Using Marson SST-1 Air Rivet Nut Tool (M39801):

• Increases Production Speed: High-RPM operation supports faster threaded insert installation in repetitive assembly environments.
• Reduces Manual Effort: Pneumatic operation eliminates the squeezing force required by traditional hand-operated rivet nut setters.
• Improves Installation Consistency: Stroke-free operation helps maintain uniform fastening performance across repeated cycles.
• Minimizes Operator Fatigue: Lightweight, balanced construction reduces strain during high-volume production work.
• Shortens Changeover Time: Quick-change installation components simplify transitions between compatible insert sizes.
• Supports Small-Fastener Applications: Specialized capacity makes the tool suitable for electronics, automotive components, enclosures, and precision assemblies.

Features:

• Pneumatic Rotary Motor: Delivers rapid threading action for efficient insert loading and tool release.
• Dual-Direction Operation: Spins onto the rivet nut during installation and reverses away after the insert is secured.
• Compact Tool Profile: Provides improved access to confined work areas and closely spaced fastening points.
• Replaceable Mandrel Hardware: Standard socket head cap screw design simplifies sourcing and routine replacement.
• Balanced Housing: Distributes tool weight to improve control during repeated trigger operation.
• Small-Diameter Thread Range: Configured for precision imperial and metric insert sizes used in light-duty assemblies.
• Low-Adjustment Setup: Eliminates manual stroke calibration when changing between compatible applications.
