Rivet Nut USA (an operating division of  Cardinal Components, Inc.) is proud to be your Preferred Authorized Bollhoff Distributor. To provide our customers with the best availability and variety, we also offer non-Bollhoff rivet nuts & fasteners.

This page details Knurled Rivet Nuts designed with a thin or near-flush head and a thin-walled round body.

Our Knurled Round Body Rivet Nut options are extensive, but two standard offerings include near-flush or thin heads (this webpage) versus flat/normal/regular heads (click here for details on regular head).

Knurled Round Body Rivet Nuts (with Thin or Near-Flush Heads) combine a reduced profile with a thinner wall, offering cost savings on materials while maintaining excellent field performance. These rivet nuts are often referred to by various names, such as “thin-walled” or “minimized profile.”

A note on terminology: the term “low profile” is sometimes used interchangeably with “near-flush head,” which can cause confusion because “low profile” is interpreted differently across the industry. To ensure clarity, we prefer to use the terms “Knurled Round Body with a Thin or Near-Flush Head” or “Knurled Round Body with a Regular Head” to describe our offerings accurately.

* Material for these rivet nuts are typically steel, with a zinc plating finish.  However, these parts can also be made in aluminum or stainless steel, neither of which require a zinc plating due to their natural corrosion resistant properties with the material itself.  To help convert the part numbers from a steel material to a aluminum or stainless steel material, please email or call us and we’ll get you into the correct part number and product.

** Plating for these parts are usually Zinc Yellow, about 98% of the time.  About 2% of the time, customer desires a grey colored Zinc Clear finish.  To convert the above part numbers from Zinc Yellow to Zinc Clear, please follow the below instructions:

  • Bollhoff does not typically offer a Zinc Yellow.
  • AVK (Swap out “4T” for Zinc Yellow and replace with “3T” for Zinc Clear)
  • Atlas (Swap out “8” for Zinc Yellow and replace with “10” for Zinc Clear)
  • Sherex (Add a “T” to the very end of the part number for Zinc Clear, ex:  CAL2-470-2.0T)
