Hi all,
I closed my pool for the first time last fall, and opened it this spring. Went great! except i had an issue with a few of the screws that go into the concrete for my safety cover. A few of them were seized up, and i was able to eventually get them up by slowly turning them with vice grips. I don't want to have to do that again, so i have been trying to find replacement screws that fit. i've tried several from Amazon that were much cheaper than the $15-$20 per brass set for the "Merlin USA" ones and none of them will actually thread in, probably a slightly different thread (i thought). I don't need the sleeve, i just need the screw. I am just trying to find new screws to put in the old sleeves.
So i sent those back, bit the bullet and bought the Merlin ones. Except, these don't fit either! they look exactly like the ones i have (albeit much cleaner) and seem to be the same size/thread pattern but they simply won't thread into the pre-existing sleeves in the concrete. I don't think i stripped the existing sleeves -- i have one of the old screws that i removed in the spring and it goes in fine.
Is there more than one thread pattern for these Merlin USA screws? These are the ones i most recently got, which also don't seem to fit: Merlin USA Anchor
