Re: Strapping of EMT
"I believe using dry wall screws ( black oxide coated) on the exterior of a building is problem."
Exterior your 100 % correct but for inside why not.If they can hold the drywall i put a toogle bolt into
We just made 9 pages and not even close to ending this

Re: Strapping of EMT
Since when is there a problem over drywall screws ? I have about 5 lbs of them holding MC straps on a building we just passed rough on a few days ago
MR JIMWALKER- The problem with drywall screws is that when shipped out from the factory in 50 lb boxes that are "BUNDLED" together on a pallet. And we all know what some people in these parts think about BUNDLING.

Re: Strapping of EMT
Lets be honest,when we see the drywallers we ask for a cup or 2 of there screws.Also learned to use a drywall screw tip instead of a #2 phillips bit.With the handy magnet screw holder on cordless strappin is fast on wood.

Re: Strapping of EMT
most quality electricians i know might use a sheetrock screw in a pinch, but always carried hex or panhead. sheetrock screws are brittle. when all the roof sheathing blew off in Florida in '90, all the roof sheathing was no longer done with sheetrock screws. most of my battery opped drills used as drivers, will break a percentage of sheetrock screws.
don't know of any code for sheetrock screws for electric, except grounding. just like irking the irkers.

Re: Strapping of EMT
Nails are not listed for box support, should I stop accepting those. I couldn't resist that one.
Back to tie wire, an inspector could reject that based on workmanship, sorry could resist another joke.
I really do not see the need to have supports listed. Anybody with common sense can see if it's going to work. You wouldn't use two lengths of 1/4 allthread to support a back to back rack of 12 - 3 inch conduits. A little extreme example, but I hope you see my point.
Having good judgement is part of being an inspector. Unfortunately, none of the inspector tests I have taken have any questions related to that. I have been on a few interview panels and it's not covered there either. Too bad.

Re: Strapping of EMT
up until '90, roof sheathing was being done all over the country with bulk drywall screws. Whether it was code or not at that time, I do not know, but it was being accepted, sort of like hanging panels with sheetrock screws (product listings generally do not list sheetrock screws for their applications).
All the press on the west coast, after whichever hurricane it was in 90, that was dealing with all the roof failures (not just shingle failures) pointed to sheetrock screws as the culprit as they have no listed shear value. The sheathing just blew off. Immediately after that was verified all the jobs that I knew about, the permitted use of sheetrock screws for sheathing was rescinded.
The electrical and gc contractors that I worked for did not want to see sheetrock screws.
As far as tie wire and ties go, the problem isn't just the looks, the listing, or even the razor ends, but ties fatigue with vibration and strain. Over time with any weight and vibration, the ties will loosen. I spent a period as a rod-buster and I have repaired almost everything in a pinch with tie wire, but I can't see it as a permanent install.
Sorry, but if I see tie wire and sheetrock screws, I always wonder what other cheap tricks have been used. I've been a bottom feeder but I didn't brag about it.

Well, after the dust settles from this thread, I hope no one ever mentions tie wire ever again.
