Challenges

The fasteners’ material had to be stainless steel since they were going to be used in food handling equipment. They would have to be installed easily, from only one side and flush with the component’s surface, to prevent food stuffs getting stuck or packaging foil getting teared. Frequent assembly and disassembly of line components for cleaning or repair purposes, required high spin out resistance of the treaded parts.

Observations

Part geometry fit for flush installation and high spin out resistance
food grade stainless steel required, less susceptible to bacterial contamination
Quick and easy, one sided fastener installation

Tubtara® Solution

Stainless steel 316 HUFO style blind rivet nut; customized grip, countersunk head for flush installation and bigger head surface contact area in the workpiece. The semi hex shank ensured increased torque-to-turn resistance. Stainless parts treated in-house with a polishing process step to cleanse surface of possible contaminants and enhance corrosion resistance.

Benefits

  • Quick and easy installation from only one side (no rear access required)
  • Cost-effective cold formed parts in 316 stainless steel
  • Inexpensive installation tooling, bringing down total installed cost
  • Part geometry ensuring flush installation and high spin out resistance
  • Strong threads, fit for repeated bolt assembly & disassembly
