Firstly threads have a mesh ratio. This is from the gaps shown in the “V” thread graphic in the top of this article. If you had no gaps then the mesh ration would be 100% and the screw would bind solid.
We will soon be purchasing a house that has a great southern exposure and will require a new roof. You mentioned that a solar company can come in while the roof is being done to install the mounts before the roofing installation is complete but I’m wondering if there is any advantage to doing that. Does it make for a cheaper solar install or simply make it more secure b/c the installer doesn’t have to search for the studs? Are roofing companies really cool w/ stopping their work while another team goes up (if time is money)?
Magnetic stud finders use powerful rare earth magnets to detect the location of metal screws or nails that hold the drywall panels in place. As you slide this type of stud finder over a wall, it is magnetically attracted to any spot directly above a nail or screw—you will actually feel it pulling in that direction, and you may even see the stud finder stick! (Most magnetic stud finders are lightweight and have magnets powerful enough that they will hold through the drywall.) Magnetic stud finders work to a depth of about ¾-inch, which is sufficient most of the time for finding studs behind standard ½-inch or 5/8-inch drywall. When you locate a nail or screw, you’ve located a stud. Because drywall fasteners are located typically 12 to 16 inches apart, it’s recommended that you move a magnetic stud finder over the wall in a sweeping “S” motion to more quickly detect one.

I mounted the controller out-of-the-way using some self-tapping screws on the underside of the wheelbarrow. I took all the ebike connectors and wrapped them up in a cut open ziplock bag and then taped the bag shut with aluminum foil tape. This makes a decent waterproof protection that keeps the connectors from shorting out when they get wet.
In Karachi, they set up offices that were cramped and sparsely furnished: oddly-assorted tables and chairs, a few pens and pencils. A peon to make the tea – the extent of their staff. They set up in Karachi, eager to be part of the great nation-building effort that Pakistan awaited. Their resources were limited, but their enthusiasm was boundless.
