These screws worked perfectly for my equipment. I needed longer screws and an easy way to tighten. So many. I will never use them all.

I am using these to add extra weight on my Technics SL1200 M7 for a counter weight to a Denon cartridge.Works perfect along with some metric weights purchased here also.
