Bollhoff  – an International Aerospace Rivet Nut Manufacturer

March 10, 2020

Nearly 100 years ago, the BF Goodrich Company invented the rivet nut, and trademarked it as the RIVNUT®. The original design and use for the RIVNUT® was for the sole purpose of easily attaching / removing rubber de-icers to aerospace / aviation wings. Today, Bollhoff is the proud owner of the RIVNUT® product line and trademark for the original rivet nut, called the RIVNUT®.aerospace rivet nut manufacturer, aerospace rivet nut

Rivet Nut USA, a division of Cardinal Components Inc., is proud to be a select preferred authorized distributor of Bollhoff and the trademarked RIVNUT® product line.

At the time that this assembly method was implemented, the world was unaware of the impact that the fastener would have on other assemblies found in manufacturing and most industry in general. RIVNUTS® have been used in aerospace, automotive, heavy truck, military, boats, lawn mowers, refrigerators, dishwashers….you name it!

United States Patent Office 2,149,199 Tubular Rivet Defined | RIVNUTS® | Rivet Nuts

“Rivnut® – The Original blind installed internally threaded, rivet, was invented (patent #2,149,199) in 1936 for the purpose of attaching a rubber aircraft wing de-icer extrusion to the leading edge of the wing. The Rivnut® riveted the aluminum wing skin to the inner aluminum spar and then accepted a mating screw to attach the rubber de-icer. This novel fastening solution allowed for easy disassembly during service, which is what a plain rivet could not offer.

The RIVNUT® fastener can be manufactured to general commercial specification, or military specification of MS27130, or an aerospace standard of NAS1329 and NAS1330. Use of the RIVNUT® expanded within the military and aerospace markets, and rapidly became a popular go-to fastening method in general industry due to its many design and assembly advantages.

To meet the rigors of aerospace requirements, standards NAS1329 and NAS1330 were developed. Standard NAS1329 specifies flat head rivet nut related aerospace performance and design requirements. Standard NAS1330 specifies countersunk rivet nut aerospace performance and design requirements. NAS1329 and NAS1330 aerospace rivet nuts could come in aluminum, steel, stainless steel or steel alloy material. These aerospace standards were established to assure repeatable and dependable performance when being used in aviation applications that demand the highest quality.

Original Equipment Manufacturers (OEMs) Now Rely on these Proven Fasteners to:

  • Perform blind installations (no access to backside of application)
  • Act like a rivet, but with disassembly convenience, when assembling two or more materials
  • Act as a nut base for secondary attachment via a mating screw / bolt
  • Installation is environmentally friendly – produces no harmful gasses, heat, dust or electromagnetic fields that affect workers (unlike welding)
  • Install into galvanized or pre-painted material without damaging surface finishes
  • Install without deforming parent material
  • Install before or after a finish is applied to a product
  • Install with non-capital investment handheld pneumatic power tools for medium to high volume applications
  • Install at a rate of 20 pieces per minute with pneumatic power tools (in best conditions)
  • Install with inexpensive hand tools, for low volume applications or field repair or consumer kit installation (use tool once and discard)
  • At the highest volumes, rivet nuts are ideal for automated assembly due to a balanced geometric shape with little dimensional variation (due to consistent nature of the cold heading manufacturing process)
  • Skilled or semi-skilled labor will have alike success doing the install on an assembly line, minimal training required
  • Install into material as thin as .020″ (0.5mm), providing strong load-bearing threads
  • Installs into a wide range of material thicknesses due to a wide grip range tolerance
  • Specific types of rivet nuts will support Grade 5 and Metric Class 8.8 mating screw proof loads
