Closed End Rivet Nut diagram, Closed End Rivnuts diagram

Closed End Rivet Nuts or RIVNUTS® are typically used in applications that require some sort of weather proofing and are frequently paired with a special seal or o-ring under the head. Closed End rivet nuts are usually round body but can also be hex body.  The closed end design provides a sealed thread, which is particularly advantageous in outdoor or harsher environmental conditions where protection from contaminants or moisture is essential.

Closed End Rivet Nuts or RIVNUTS® come in a range of material choices, including aluminum, steel with zinc plating, and stainless steel. Whether you are using the rivet nut in open end or closed end configurations, you can expect the same level of thread engagement—typically ranging from 4 to 7 threads, depending on the specific style. This ensures consistent and secure fastening for your application.

Closed End Rivet Nut, Closed End Rivnut, Bollhoff Closed End Rivnut The main difference between open end and Closed End Rivet Nuts or RIVNUTS® is whether a bolt can pass through them. In an Open End Rivet Nut, a bolt can go all the way through the threads. But in a Closed End Rivet Nut (also called a RIVNUT®), the bolt will stop when it reaches the sealed end. When using a Closed End Rivet Nuts or RIVNUTS®, it’s important to make sure the bolt is not too long, or it might not fit properly inside the rivet nut.
