electrical box cover screws I recently removed lots of electrical covers to do some painting. I noticed that almost all of the screws for the covers have a tiny square black washer on them. I was careful to reinstall the cover screws with these washers. Still, it’s possible to weld thin sheet metal using the MIG (GMAW), TIG (GTAW), and stick (SMAW) processes. But MIG and TIG provide the best results. This article will teach you how to weld thin gauge metal using each arc welding process and present the common pitfalls beginners make.

These Square D by Schneider Electric Load Center Cover Replacement Screws (6-Pack) fit many types of service entrance devices and . The most common size screw to use in an electric box is a 6-32 flathead screw. For heavier applications, like ceiling lighting and ceiling fans, an 8-32 screw will work better. Ground screws in electrical boxes are always 10-32 . I need additional screws for several electrical boxes, some mounting a fixture, some for switches, some for covers. I just want to buy some boxes of machine screws to cover the various sizes of commonly used screws in electrical boxes and fixtures. I think the threads on the most common screws are 6/32, 8/32 and 10/32. If the box is a round type, as commonly used for ceiling lights, then an 8-32 screw would be appropriate. If the box is rectangular, as used for wiring devices (switch, outlet, etc) then a 6-32 screw is what you will need. I have successfully used coarse thread #6 drywall type screws in both type of boxes . :whistling2:
I recently removed lots of electrical covers to do some painting. I noticed that almost all of the screws for the covers have a tiny square black washer on them. I was careful to reinstall the cover screws with these washers. I have bought panel screws in the electrical department (not the hardware department) at Home Depot. However, they were not specific to any brand of panel. If yours are an oddball size call your local electric supply house. Around here we have Colonial Electric Supply. Sent from my LG-D415 using Tapatalk Install the cover on the box with the required 8/32 screws and cover the plastic siding block with your removable facia piece. If the back of that cylindrical opening is marked UL, ULC or ETL then IT is an electrical box and it can be covered with a standard plastic round cover plate or with the larger finish style plate. The cover screws in my GE panel are 10x24x3/4" pan head machine screws. Went to my electrical supply house-nope, Tractor Supply-nope, Fastenal- would have to buy box of 100, local hardware was out of the 3/4" plated screws but had them in stainless. 31 cents each and 2 gallons of gas for my truck[emoji3525].

The model number you gave is for the cover, not the panel. That “pole” is actually a depth adjustment screw. If you set a flushmount box too deep, you could adjust the entire bus bar and breakers (which were spring mounted) outwards so the breakers would sit flush in the cover holes. Being a smaller panel you have one screw in the middle. The ones in question are two-start screws. They go in twice as far per turn. Grandfather was a forty year lathe operator a Cincinnati Milacron. Oh, and you won't find those in the hardware bins, and even if you did, they wouldn't be legal to use. Panel cover screws do not have threads all the way to the end and have a blunt tip. Mark
Correct. In a metal box, the ground wires from the cables go to the box's grounding screw first. Then, the switches pick up ground via their mounting screws, and receps pick it up either through a "self-grounding" feature against the screw threads, or via hard flush metal yoke-box contact, or via a ground pigtail to the screw or a clip. On the heaviest (say 40-50 lbs and over), the manufacturer added a cable that was supposed to be attached directly to the electrical box. So when the screws failed, the cable would stop the fixture from falling to the floor. :huh: Nice design.
