This product appears to be a kit that includes carbon steel flat, waterproof, and long blind rivnut tools, along with reverse nutsivet rivet nuts. This type of kit is designed for installing rivet nuts (also known as rivnuts or nutserts) which provide a threaded insert in materials that are too thin to be tapped or where access is only available from one side (blind installation).

Key Components and Features:

• Carbon Steel: Indicates the material of the rivnut components (and potentially the tool) is carbon steel, offering good strength and durability for many applications.
• Flat Head: Refers to the head style of the rivet nuts. A flat head typically sits flush or near-flush with the surface of the material, providing a neat finish.
• Waterproof: Suggests that the rivet nuts, or the installation method achieved with this kit, can create a seal against moisture, making them suitable for applications where water ingress is a concern. This might involve a closed-end rivnut or a sealing washer.
• Long Blind Rivnut: “Long” likely refers to the length of the rivnut, allowing for secure fastening in thicker materials or providing a longer thread engagement. “Blind” indicates that the rivnut can be installed from one side of the workpiece.
• Tool Kit: Implies that the package includes all necessary tools for installing the rivnuts, such as a rivnut setting tool (manual or powered), mandrels, nose pieces, and potentially a range of rivnut sizes.
• Reverse Nutsivet / Rivet Nut: These are interchangeable terms for the same fastener type. They are internally threaded inserts that are installed into a pre-drilled hole from one side, creating a permanent thread for attachment. “Reverse” might imply a specific installation or design characteristic, but generally, it refers to the basic function of a rivnut as a threaded insert.

Typical Applications:

• Automotive Industry: Attaching components to vehicle panels, chassis, or interiors, especially for lightweight or thin-gauge materials.
• Sheet Metal Fabrication: Creating load-bearing threads in sheet metal where welding or tapping is not feasible.
• General Manufacturing: Assemblies where components need to be easily attachable/detachable from one side.
• Marine Applications: The “waterproof” feature makes it suitable for boats and other marine equipment where exposure to water is common.
• HVAC Systems: For attaching panels and components where a sealed connection is beneficial.
• Appliances: Securing parts in household appliances.

Advantages:

• Blind Installation: No access required to the back side of the material.
• Creates Permanent Threads: Provides strong, reusable threads in thin materials.
• Versatile: Can be used in various materials including metals, plastics, and composites.
• Strong Fastening: Offers good pull-out resistance when properly installed.
• Waterproof Option: Specific design elements cater to moisture-sensitive environments.
• Convenience: A complete kit ensures all necessary tools are available for immediate use.
