8 Pieces 180 Degree Folding Flush Hatch Hinges, Sewing Machine Tray Table Hinge Table Hinge for Multiple Folding Table Tops Computer Desk Sewing Machine

As much as I want to find some like this less expenssive, they just do not exist; even on Alibaba. Some are tight, some are lose, but for my application they work great. I have bought many.

Good solid hinges

a little loose but ok

These were OK structurally, just not the right fit for my intended purpose, so I returned them.

I got these to make folding cucumber trellises that can fold flat when not in use. Perfect size for 1 x 2 wood

read some complaints about these hinges, they arrived on time, metal is thick, heavy duty, but they are not precission, some are tight , some are loose, sloppy, the sloppy ones I put on my vise and tap the pin a couple of times and they tighten up, if you wanted these for a precise fit like on doors, not recommend. but for the price , they served my purpose, ( CatSnipeCosta )

I should have expected a lot of ‘slop’ in these cheap hinges. The price was too good not to test out. I tried them in 2 different projects and both times proved to be too flimsy/ weak to hold steady. They are made to fit into tight places but I wouldn’t trust a hinge without at least2 or 3 of these and that would negate the fact that they are a small profile to fit in tight places.

These were the perfect hinges for an older changing table! Heavy weight. Perfect fit. Replaced the ones I put in a "safe place" when I refurbished it!
