The Marson 39302 Poly-Nut Thread-Setter Kit (39302) is a manual, plier-style fastening system designed to install SAE threaded inserts in thin materials and structures where rear-side access is limited. The included tool creates secure, load-bearing threads without requiring welding or conventional tapping, making it suitable for sheet metal, steel, automotive components, fabrication projects, and industrial assemblies. Its mechanical leverage system, adjustable stroke, and interchangeable mandrels support controlled installation of #8-32, #10-32, and 1/4-20 Klik Poly-Nuts. The kit also includes 52 assorted inserts and a molded carrying case for immediate use, organized storage, and convenient transportation.Key Features and Benefits: Manual Plier Operation: Provides controlled threaded insert installation without requiring electricity, batteries, or compressed air. Multiple Thread Sizes: Includes mandrels and nosepieces for #8-32, #10-32, and 1/4-20 SAE inserts. Adjustable Setting Stroke: Positive-stop locking mechanism allows the installation stroke to be configured for consistent insert compression. Mechanical Leverage: Long, heat-treated steel handles and a specialized fulcrum design reduce the effort required during installation. Complete Fastening Kit: Includes the installation tool, 52 assorted Klik Poly-Nuts, service wrench, instructions, and carrying case. Portable Configuration: Manual operation and organized storage make the kit suitable for workshops, job sites, and mobile repairs.Specifications: Product Name: Marson 39302 Poly-Nut Thread-Setter Kit (39302) Model Number: 39302 Included Tool: Marson 39300 rivet nut installation tool Tool Capacity: SAE threaded inserts up to 1/4-20 in steel Included Thread Sizes: #8-32, #10-32, and 1/4-20 Included Mandrels and Nosepieces: #8-32, #10-32, and 1/4-20 sets Fastener Capacity: 52 assorted Klik Poly-Nuts Included Fastener Assortment: 12 each M57425, M57435, and M57445, plus 16 M57455 Klik Poly-Nuts Tool Body Material: High-strength aluminum alloy Handle Material: Forged, heat-treated steel Operation Type: Manual plier-style operation Product Weight: Approximately 3 lb Package Contents: One Marson 39300 tool, three mandrel and nosepiece sets, 52 assorted Klik Poly-Nuts, one wrench, instructions, and one molded plastic carrying caseHow to Use: Select the Installation Hardware: Choose the mandrel and nosepiece that match the thread size of the Poly-Nut being installed. Install the Mandrel: Thread the selected mandrel securely into the tool head. Attach the Nosepiece: Fit the corresponding nosepiece and tighten it with the supplied wrench. Adjust the Stroke: Configure the positive-stop mechanism according to the insert size and thickness of the workpiece. Load the Poly-Nut: Thread the insert onto the exposed mandrel until its head rests against the nosepiece. Position the Insert: Place the Poly-Nut completely into a correctly sized, burr-free mounting hole. Set the Fastener: Squeeze the handles firmly to retract the mandrel and collapse the insert body against the reverse side of the material. Check the Installation: Confirm that the Poly-Nut is securely compressed, correctly aligned, and unable to rotate in the hole. Release the Tool: Open the handles and rotate the tool counterclockwise to unthread the mandrel from the installed insert. Attach the Component: Secure the required component using a screw or bolt that matches the installed Poly-Nut thread size.Benefits of Using Marson 39302 Poly-Nut Thread-Setter Kit (39302): Creates Threads in Thin Materials: Provides secure thread engagement where the workpiece lacks sufficient thickness for conventional tapping. Supports Blind-Side Assembly: Installs threaded attachment points without requiring access behind the panel or structure. Eliminates Welding Requirements: Creates captive threads without applying heat that could damage coatings, finishes, or surrounding materials. Promotes Consistent Installation: Adjustable stroke control helps achieve uniform insert compression across repeated fastening tasks. Handles Multiple Applications: Three included SAE thread sizes support common automotive, fabrication, maintenance, and industrial requirements. Provides Immediate Usability: The included assortment of Klik Poly-Nuts allows common installation work to begin without purchasing fasteners separately.Features: Cushioned Vinyl Grips: Provide a more comfortable gripping surface during repetitive manual operation. Lightweight Tool Body: Aluminum alloy construction balances portability with structural support. Quick-Change Components: Interchangeable mandrels and nosepieces allow transitions between supported thread sizes. Positive-Stop Mechanism: Locks the selected stroke setting to support repeatable insert deformation. Compact Tool Profile: Plier-style configuration provides access to confined or restricted installation areas. Compartmentalized Storage: Molded plastic case protects the tool and organizes the mandrels, nosepieces, wrench, and fasteners. Assorted Insert Supply: Includes four Klik Poly-Nut part-number configurations for different supported thread and grip requirements.
