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
