Nageshi screws: 4.2 x 65mm, approximately 250 screws. (The box originally contained 400 screws, but approximately 150 were used, so this is the remaining amount.) Thin shaft course thread screws: 3.3 x 30mm, approximately 900 screws. I purchased these for DIY projects, but no longer need them, so I am selling them. The boxes have been opened, but the remaining screws are unused. For shipping, I will fold the boxes and put the screws in bags!
