Carl,<div>I have used fablok fasteners and "never drop" or toggle anchors for very similar applications and liked them.

I have a couple of<br>> upcoming jobs where I am attaching PV mounting structure as follows<br>> Job 1) LFoot to metal roof into Z purlin, and Job 2) FastJack to metal<br>> roof into bar joist.<br>> <br>> In both of the applications I'm considering the Tek screw type<br>> attachment to the building steel. Both the L foot and FastJack are<br>> sized for a 5/16 - 3/8 lag or bolt. Most of the self tappers I see<br>> are 1/4" max diameter. Should I be concerned about the undersized fit<br>> of the fastener in the mounting attachment or are there large Tek type<br>> screws out there I'm not finding?<br>> <br>> Does anyone have pullout strengths for this type of attachment?<br>> <br>> With Regards<br>> Carl Adams<br>> NABCEP Certified PV Installer<br>> SunRock Solar, LLC<br>> <br>> On Thu, Feb 5, 2009 at 6:51 PM, Peter Parrish<br>> <peter.parrish@calsolareng.com> wrote:<br>> > Does anyone have a source for stainless steel, self tapping Tek screws?
