M3 x 10mm Steel Rivet Nut Flat Flange Knurled Open Type Zinc Plated

Open-End Knurled Rivet Nuts with Flat Flange – Carbon Steel, Zinc-Plated

Open-end rivet nuts, also known as rivnuts, nutserts, or threaded inserts, provide a strong reusable thread in sheet materials too thin for traditional tapping. These blind nuts are designed for single-sided installation, so you can create secure, load-bearing connections even when you can’t access the back of the panel. Once set, they allow bolts or screws to be inserted and removed multiple times without damaging the base material.

A flat flange sits almost flush with the surface, spreading the clamping force evenly and helping to reinforce thin or soft materials. The knurled body bites into the parent material, dramatically increasing resistance to spin-out and pull-through, especially in soft metals or plastics. As an open-end style, these rivet nuts accept bolts that run all the way through, making them ideal for longer screw lengths or studding. Made from durable carbon steel and coated with corrosion-resistant zinc, they are available in various thread sizes and grip ranges to suit different applications.

Key Features & Benefits

• Single-sided installation: No need to access the reverse side, perfect for enclosed sections or blind cavities.
• Strong internal thread: Creates a load-bearing thread in sheet metal, composites, fibreglass or plastics.
• Knurled body for extra grip: Prevents rotation and increases torque-out resistance in soft materials.
• Flush flat flange: Offers a neat, near-flush finish while distributing load evenly and protecting the substrate.
• Open-end design: Allows longer screws or threaded studs to pass through for added flexibility.
• Durable steel construction: Carbon steel body with zinc plating for corrosion resistance and long service life.
• Versatile applications: Ideal for automotive, HVAC, construction, appliance manufacturing and general engineering where a strong, reusable thread is required.
