Sheet-to-Sheet Attachment
Allows permanent joining of two metal sections and metal to PCB/plastic panels- Alternative to riveting and welding.
- No special installation equipment required.
- Flush mounted on both sides.
- Minimal space requirements.
- Can be installed blind into bottom (panel 2) sheet.
- Can be concealed with paints and powder coatings.
Type SFK fasteners create a permanent, flush joining of metal to PCB/plastic panels. The fastener has two separate joining profiles. Squeezing the fastener into place causes a cold-flow of the metal panel material into the fastener’s clinch profile and a broaching fit of the knurl into the PC Board or plastic panel.
Unlike rivets that “bulb” during installation, the ultimately flush profile of SpotFast fasteners allows for unobtrusive attachment requiring minimal space. A smooth surface is retained for finishing and fasteners can be concealed easily with paints or powder coatings.
Tube Bushings
(6) High strength, threaded fastener designed for aluminum extrusionsHigh 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
