304 Stainless Steel Flat Head Threaded Rivet Nut Kit - 5/16-18 UNC for Secure Metal Fastening

This rivet nut kit offers a straightforward solution for adding threaded anchor points in thin sheet metal, aluminium, or plastic where access is limited to one side. Made from 304 stainless steel, each rivet nut is designed to resist corrosion, making it a practical choice for automotive repairs, shelving assembly, or equipment mounting. The flat head profile sits flush against the surface, reducing the risk of snagging and providing a neat appearance. Whether you need 20 or 40 pieces, this kit gives you the fasteners required for reliable installations.

Features and Construction

Each rivet nut is built to a precise specification, ensuring consistent performance during installation and use. The flat head design and standard UNC threading make these rivet nuts compatible with common tools and bolts.

Material and Build

Constructed from 304 stainless steel, these rivet nuts offer good corrosion resistance for indoor and outdoor use. The material withstands moisture better than standard carbon steel, extending the lifespan of the fastener in damp environments. The flat head has a diameter of 1.5cm and a height of 0.07cm, providing a low-profile finish.

Size and Practical Fit

Each rivet nut features 5/16-18 UNC threads, a body diameter of 0.4 inches (10.2mm), and a total length of 0.75 inches (1.8cm). The installation drilling size is 0.4 inches to match the body diameter, and the grip range covers 0.00 to 0.10 inches (0.1-0.3cm). This sizing is suitable for thin materials up to about 2.5mm thick.

Uses and Placement

These rivet nuts are designed for applications where standard nuts and bolts cannot be used because the rear of the material is inaccessible. They are commonly used in automotive bodywork, metal sign installation, or furniture assembly.

Event or Professional Use

In a professional workshop or garage, these rivet nuts allow mechanics and fabricators to add threaded inserts in vehicle panels, brackets, or chassis components. The 304 stainless steel ensures the fasteners remain rust-free during washdowns or damp conditions.

Everyday Home Use

For home DIY projects, these rivet nuts can be used to attach shelving brackets, mount fixtures to metal cabinets, or repair stripped threads in appliances. The flat head sits flush, keeping surfaces smooth and safe.

Benefits and Buying Value

This kit offers a practical way to add strong, removable threads to thin materials. Choosing between 20 or 40 pieces allows you to match the quantity to the job size without overspending.

Reuse and Low Maintenance

Once installed, these rivet nuts can be used repeatedly, allowing bolts to be removed and reinserted as needed. The stainless steel material requires minimal maintenance and resists corrosion over time.

Why Choose This Product

The combination of 304 stainless steel, a compact flat head, and standard 5/16-18 UNC threading makes this kit a straightforward choice for many fastening tasks. The clear specifications help ensure the correct fit for your project.
