These hinges came in a small tightly-packed box along with a plastic bag of screws. All of the hinges were in perfect condition; no marks, scratches or bends in the metal. They are standard thickness, as expected. The screws are the standard size screws for doors. Some other reviewers mention they wish the screws were longer; however, this size is the standard size screw and you should expect them to send the standard size; not longer than standard. If you are not comfortable with the standard screws, then get longer. But, you're using 3 screws per hinge-side. You shouldn't be hanging off your doors and 2 hinges with 3 screws per hinge-side should hold the weight of a hollow or solid core door without issues. But, if you want to hang off your doors or have kids that could potentially swing on them, then go for longer screws at your own cost.
In my particular case, I did NOT remove or even attempt to remove the pin from the hinges. I didn't need to. I was replacing old doors in my house so used the existing slots of the old hinges on the door frames and measured them to match the new doors. Then I applied the new hinges to the frames and had my son hold the door up to the new slots I cut in the door and attached. So, no need to remove the hinges.
I got the set of 18 and will buy this same brand if I need more in the future (regardless of count).
On another note, I bought a door hinge jig that I used to cut out the slots for the hinges with my router and the hinges fit perfectly with the template-cut slots I made. So, I know they were machined properly. I highly recommend a jig for cutting hinge slots in doors if you own a router. Very big time saver and work super well with these hinges.
