M6x16 內六角沉頭螺絲

The hex socket drives smoothly without stripping, and the countersunk head sits perfectly flush on the mounting plate. A solid little screw for keeping things snug on the machine.

Installed these on the SIEG 7650 machine needing flush mounting, and the hex socket engaged cleanly without stripping. They hold tight under vibration and didn't require any re-torquing after a few cycles. A solid, precise fit for the intended application.

The countersunk head sits perfectly flush in the mounting holes, so nothing snags when I'm clamping workpieces. Threads engaged smoothly on the 7600 without any wobble, and they've held firm through a full day of milling.
