Tube Bushings
PEM® Brand Fasteners for Metal Sheets and Panels
High strength, threaded fastener designed for aluminum extrusions
High strength, threaded fastener for aluminum tubing
Designed with a double clinch feature on both ends, TBA™ and TBFA™ (flange style) fasteners firmly lock into place in the aluminum tube during installation.
This datasheet showcases custom-designed parts developed for square and rectangular aluminum tubing. Samples of these solutions are available from stock.
The datasheet illustrates PennEngineering’s expertise in creating strong, reliable threads in tubing applications. Since dimensions may vary with tube size and wall thickness, our engineering team can help tailor the design to your specific needs. Contact us to explore the best solution for your application.
Note: Additional sizes available on special order. Contact us for availability.
High strength, threaded fastener for aluminum tubing
Designed with a double clinch feature on both ends, TBA™ and TBFA™ (flange style) fasteners firmly lock into place in the aluminum tube during installation.
- Designed for square or rectangular aluminum tubing
- Connects two sides of the tubing
- High strength thread (meets Class 10 proof load requirements when the effective thread depth is greater than 1.5 times the major diameter), and high torque resistance
- Improve the strength and Noise, Vibration, and Hardness (NVH) performance
- Installs into round holes
