I bought this instead of going to my local hardware store because they only sell the porcelain equivalent. I am writing because I missed information from other reviews. I am NOT an electrician. Firstly, it is a normal UL listed lamp holder for USA. Regular screws are used as can be seen in the attached image as one was asking what the back looks like. I'm not sure why some are talking about flat screws. I think they don't know how to bend wires around screws here (btw if you don't know how it matters how wires should be bent around screws, call a pro!). Second shines as if they do not come with the bottom! This is normal again and the ground is at the light switch itself. If you think the "green" screw is "neutral" don't do the wiring yourself, call a professional! You don't know what you are doing and you will either injure yourself, use the wrong wire or start a fire! Call a professional!
