Marson 104-Piece Rivet Nut Setter Kit (39301)

The Marson 104-Piece Rivet Nut Setter Kit (39301) is a manual fastening system designed to install threaded inserts and rivet nuts in thin materials such as sheet metal, rigid plastic, and fiberglass. The kit creates permanent internal threads in applications where conventional tapping is impractical or access to the reverse side of the workpiece is limited. Suitable for automotive repair, industrial maintenance, fabrication, and general assembly, it can be used to restore stripped mounting points or add secure threaded anchors to panels and components. The kit includes the M39300 Thread-Setter, interchangeable installation hardware, 103 assorted Klik Rivet-Nuts and Klik Poly-Nuts, a service wrench, and an organized carrying case.

Key Features and Benefits:

• Quick-Change Mandrel System: Allows users to transition between compatible thread sizes efficiently during different fastening tasks.
• Adjustable Stroke: Controls the compression distance to support proper installation across varying insert sizes and material thicknesses.
• Positive-Stop Locking: Maintains the selected setting depth for consistent results during repetitive installations.
• Patented Fulcrum Pin: Helps prevent pivot rotation and reduces wear on the tool during repeated handle operation.
• Comfortable Handling: Cushion-molded vinyl grips provide a secure and comfortable surface during manual use.
• Complete Fastening Assortment: Includes multiple mandrels, nosepieces, and 103 threaded inserts for immediate project use.

How to Use:

• Select the Insert Size: Identify the thread size of the rivet nut or threaded insert required for the application.
• Choose the Tooling: Select the mandrel and nosepiece that correspond to the chosen insert size.
• Configure the Tool: Install the mandrel and nosepiece into the M39300 tool head and secure them with the supplied wrench.
• Prepare the Mounting Hole: Drill a correctly sized hole in the workpiece and remove any burrs, dirt, or debris.
• Load the Insert: Thread the rivet nut onto the mandrel until its flange rests against the nosepiece.
• Adjust the Stroke: Set the compression distance according to the insert dimensions and material thickness, then lock the adjustment in place.
• Position the Insert: Place the rivet nut completely into the prepared hole with its flange seated against the workpiece.
• Set the Fastener: Close the handles firmly to compress the insert body and form a secure flange behind the material.
• Check the Installation: Confirm that the insert is properly aligned, firmly seated, and unable to rotate in the hole.
• Release the Tool: Use the reverse mechanism to unthread the mandrel from the installed rivet nut.
• Attach the Component: Secure the required part using a compatible machine screw or bolt.

Benefits of Using Marson 104-Piece Rivet Nut Setter Kit (39301):

• Creates Threads in Thin Materials: Provides dependable threaded mounting points where the substrate is too thin for conventional tapping.
• Supports Blind-Side Installation: Allows fasteners to be installed when access is available from only one side of the workpiece.
• Eliminates Welding Requirements: Creates permanent threaded anchors without welding equipment, heat, or extensive surface preparation.
• Provides Portable Operation: Manual design enables use in workshops, field repairs, and locations without electrical or pneumatic power.
• Improves Installation Consistency: Adjustable stroke and positive-stop control help maintain uniform compression across multiple fasteners.
• Simplifies Inventory Management: The molded case keeps the tool, inserts, mandrels, nosepieces, and wrench organized in one location.

Features:

• Lightweight Structural Body: Aluminum alloy construction provides rigidity while keeping the tool manageable during extended use.
• Reinforced Upper Handle: Forged and heat-treated steel supports the leverage required for threaded insert compression.
• Four-Size Installation System: Interchangeable components support common imperial thread sizes for varied repair and assembly work.
• Compartmentalized Storage: Molded case interior separates small fasteners and installation hardware for easier identification.
• Self-Contained Manual Design: Operates without batteries, electricity, compressed air, or external hydraulic equipment.
• Multi-Material Application: Suitable for compatible thin metal, rigid plastic, and fiberglass workpieces.
• Serviceable Head Assembly: Supplied wrench supports efficient mandrel and nosepiece removal, installation, and maintenance.
