U-Nut Threaded Fasteners

Self-Retaining U-Nuts

Tapped Barrel - Long-Throat LUGS

Self-Retaining U-Nut Threaded Fasteners from A. Raymond Tinnerman Industrial are used to provide simple, quick attachment of mating panels. U-Nuts self-retain in screw-receiving position. This tapped barrel U-Nut requires no special tools and is easy to assemble.

  • Preferred alternative for machine screws
  • Barrel comes in free-spinning options and prevailing torque
  • The U-Nut is positioned onto the panel edge and over the panel hole
  • Self-retention feature eliminates costly welding and clinching costs and it improves assembly time
  • Helps fix misalignment in panel mounting holes
  • Part won’t freeze on screw threads and does not move as the screw is driven
  • U-Nut threaded fasteners disassemble easily and reliably and the part is highly serviceable
  • Can be used wherever a screw or bolt is used and in place of clinch nuts and weld nuts
  • The tapped barrel strength equals that of the screw
