[RE-wrenches] SS Tek Crews

[August Goers]

I've used the attached tek screws for a couple of steel roof applications - if you look at the "Performance Data" you'll note how strong they are. Similar versions are available in SS. -August

Carl,
I have used fablok fasteners and "never drop" or toggle anchors for very similar applications and liked them. I just don't trust Tek Screws for attaching racking systems.

Never drop:

Fablok:

Both require additional work to install, but are worth knowing the connection is solid (no spinnners).

Cheers,
Tommy Jacoby
