Marson SRN-2 Swivel Klik-Turn Rivel Nut Setter (39400)

The Marson SRN-2 Swivel Klik-Turn Rivel Nut Setter (39400) is a professional manual tool designed to install threaded rivet nuts in thin materials and restricted work areas. Its 360-degree swivel head features a positive-ratchet locking mechanism that secures the tool in more than 40 positions, allowing operators to reach fasteners at difficult angles. The quick-change mandrel system, adjustable stroke control, and extended handles support efficient installation of imperial and metric inserts in automotive repair, fabrication, maintenance, and industrial assembly applications.

Key Features and Benefits:

• 360-Degree Swivel Head: Rotates fully to provide access to fasteners positioned in confined spaces and difficult working angles.
• Positive-Ratchet Lock: Secures the head in more than 40 positions to maintain stability during installation.
• Quick-Change Mandrel System: Allows compatible mandrels and nosepieces to be changed efficiently without additional tools.
• Adjustable Stroke Control: Regulates insert compression to support consistent installation across different material thicknesses.
• Extended Handle Leverage: Reduces the manual force required to set larger threaded inserts.
• Integrated Component Storage: Built-in storage holes keep compatible mandrels and nosepieces accessible during use.

How to Use:

• Select the Components: Choose the mandrel and nosepiece that match the thread size of the rivet nut being installed.
• Install the Mandrel: Secure the selected mandrel in the tool and attach the corresponding 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 mandrel length and compression distance using the adjustment knob and lock nut.
• Load the Rivet Nut: Thread the insert onto the mandrel until its flange rests against the nosepiece.
• Position the Swivel Head: Rotate the tool head to the required angle and engage the ratchet lock to hold it securely.
• Insert the Fastener: Place the rivet nut completely into the prepared hole with its flange seated against the material.
• Set the Rivet Nut: Squeeze the handles firmly to compress the insert against the reverse side of the workpiece.
• Check the Installation: Confirm that the insert is securely seated, properly aligned, and unable to rotate inside the hole.
• Release the Tool: Open the handles fully and rotate the mandrel knob to unthread the tool from the installed insert.

Benefits of Using Marson SRN-2 Swivel Klik-Turn Rivel Nut Setter (39400):

• Improves Restricted-Area Access: Swivel-head operation enables threaded insert installation in corners, recesses, and irregularly positioned panels.
• Promotes Consistent Results: Adjustable stroke control helps prevent under-setting, over-compression, and insert damage.
• Reduces Operator Fatigue: Extended handles increase mechanical leverage during repetitive or larger insert installations.
• Minimizes Setup Time: Quick-change installation components simplify transitions between supported thread sizes.
• Supports Blind-Side Fastening: Creates secure threaded mounting points when the reverse side of the workpiece is inaccessible.
• Provides Portable Operation: Manual design eliminates the need for compressed air, batteries, or electrical power.

Features:

• Multi-Position Ratchet Head: Holds the tool at numerous working angles without allowing unwanted head movement.
• Optimized Fulcrum Mechanism: Pivot design improves force transfer and supports smooth handle operation.
• Lightweight Structural Body: Die-cast aluminum construction balances portability with mechanical stability.
• Reinforced Upper Handle: Heat-treated steel withstands the stress generated during threaded insert compression.
• Ergonomic Hand Grips: Shaped gripping surfaces improve control and comfort during repeated use.
• Imperial and Metric Capability: Supports common SAE inserts and compatible 6mm metric hardware.
• Onboard Tooling Storage: Integrated threaded holes provide convenient access to spare installation components.
