FAST AND EASY!
Automatic-Fastening Sets create a friction-based connection between any two t-slot aluminum extrusion profiles from the same line. They allow for subsequent adjustment because the fasteners are only screwed into one profile. These Fastening Sets can be installed easily into existing constructions. The profiles do not need to be machined in order to use the Automatic-Fastening Sets.
The Fastener is screwed into a profile groove in the end face, the thread being cut automatically. Use of a lubricant is recommended.Note:
All Fasteners with a through bore for the fastening screw have a counter-clockwise thread on the outside in order to prevent the Fastener twisting when the screw is tightened.
L-Keys from item are the ideal tool for tightening the screws of the Automatic-Fastening Set
Automatic-Fastening Sets 6, 8, 10 and 12 also have an anti-torsion feature. Once the profile has been pre-assembled, this feature can be deployed by unscrewing the fastener sufficiently so that the end of it projects into the profile groove.
Automatic-Fastening Sets should always be used in pairs.
