I ordered these to replace some missing case thumb screws on an older Corsair Crystal 280x which i measured to be M4x11mm. I used the M4x10mm for the top and side glass panels. These have no large flat screwdriver slot on top like the original screws and the head is the same diameter as the original at around 12mm. The head is shorter at 4mm vs the original 5mm and overall makes the fit and finish look less utilitarian and along with the really nice finish cleans up the exterior quite nicely.

Was improving the mounting hardware on my motorcycle for the GPS which was supplied with screws, which require a screwdriver or Allen key and may be lost at some point. The thumb screw is the answer. Verified the length and size before ordering and it worked perfectly. Just a drop of thread fastener and ready to ride. Thx
