Set Screw, M4x8, Socket Flat Point

The flat point of these M4 screws seated perfectly in the cross slide nut groove, and the 8mm length was exactly what my SC4 needed. Took just a few minutes to swap out the old ones, and the backlash is noticeably tighter now.

Installed these on my SC4 lathe’s cross slide nut and they threaded in perfectly right out of the bag. The flat point seats nicely against the feed screw without binding.

Was a bit worried about the fit on my SC4 lathe's feed screw nut, but both screws seated perfectly and the flat point sits flush against the shaft. No wobble or play after tightening them down.
