Knurled Round and Half-Hex Body Rivet Nuts are sometimes called the “thin wall” or “low profile” series. Although this phrase has been used in the industry for a long time, they are not always low profile. Often these rivet nuts have a thinner wall (or low profile) which provides a more cost-effective option. These fasteners are unique because they are available with a thin or flush head or a regular/normal head with a round body and another option  is the normal head with a half-hex body. No matter which option you choose, these Knurled Round and Half-Hex Rivets Nuts were designed to create a strong, load-bearing threaded connection in sheet metal, tubing, and thin-wall materials. These industry-leading fasteners are commonly used in applications for the automotive, aerospace, construction, and manufacturing industries, providing an efficient way to add threaded fasteners to materials where standard nuts and bolts cannot be used.

The Knurled Round and Half-Hex Body Rivet Nuts (aka “Thin Wall” or “Low Profile” series) are characterized by their solid design, incorporating either a knurled (vertical lines) round body or half-hexagonal body shape.

  • The knurled surface can help increase the grip of the fastener when it is installed, preventing slippage under torque.
  • The half-hex body option was designed to provide a superior level of anti-rotational resistance, specifically for applications that are subject to high stress or vibration.

Knurled Round and Half-Hex Body Rivet Nuts are made from high-quality materials such as steel, stainless steel, or aluminum, each offering specific advantages for different applications. For example, stainless steel rivet nuts are often selected for their corrosion resistance, while aluminum is used when a lightweight option is necessary. They come in a variety of thread sizes and grip ranges for both Unified and Metric options to meet the needs of your application.

Advantages of Using Knurled Round and Half-Hex Rivet Nuts

The primary benefit of this internally threaded blind fastener is its ability to a create strong, reliable threaded connection in materials where traditional fasteners (such as a nut and bolt) may be impractical. Installing a rivet nut only requires access from one side (the front side facing the installer), a feature particularly useful in tight spaces or where access to the backside (blindside) of the parent material is not available. Additionally, the knurled design on the body will help ensure the fastener does not slip or rotate, making it better suited to applications that may experience some vibration.

Installation is also simplified with pneumatic or hand tools designed specifically for these thin wall fasteners, reducing labor time.

Knurled Round and Half-Hex Body Rivet Nuts (aka “Thin Wall” or “Low Profile” series) provide a reliable, efficient solution for adding threaded fasteners in challenging applications, offering strength, ease of installation, and versatility for high-performance demands.
