<div>Hey Darryl,</div>
<div><br></div>
<div>I agree with Jason. We've done some commercial S5 systems and we pre-tighten with a cordless driver and then two guys follow with a couple of manual torque wrenches - it takes but a few seconds to turn the final 1/2 turn to the right torque - felt and confirmed by human feel and eyes. We used digital beeping torque wrenches for a while but they would eventually fail. Our tool of choice now is a 1/4" drive hand held good - ole "click" type torque wrench. Worth the very little bit of extra time in my book to know it's done right.</div>

<blockquote type="cite">Hello Darryl,<br>I am a big fan of manually tightening all bolts and panel clips on any array. I have done this on a MW tracker and racking systems on schools, which were checked by a special inspector who required them to be hand torqued and yes it's a lot, but in many peoples minds hand tightened is worth it. I do know folks who use a cordless drill and turn the setting down so as not to strip bolts and then go through and torque by hand.<br>
<br>Mostly this is a personnel opinion on the process and wanted to relay my experiences.<br><br></blockquote>

<blockquote>Hi all, I need advice<br>I am soon starting a 1000 module system, uning top down mounts, What power tools will tighten to torque specification? I will want to tighten each SS 1/4" nut on bolt to proper specs. This is about 2000 bolts, so i want a power tool, either air or battery electric, or electric that will tighten to specification.<br>
