براغي رأس مقبس M4-0.7 × 6 مم | رأس مسطح بمقبس سداسي | كاملة الخيوط | ستانلس ستيل 316 (1200 / عبوة)

I've been using these M4 screws for mounting brackets on a CNC machine, and the 316 stainless steel is a big step up from the cheaper alloys I tried before—no rust or galling issues so far, even in a slightly damp workshop. The hex socket drive sits flush with the flat head, which makes them perfect

Got these for a tooling fixture I’m building, and the 316 stainless feels solid—no burrs or rough edges out of the box. The flat head sits flush perfectly in countersunk holes, which saved me a lot of filing time. For 1200 pieces at this price, they’re a no-brainer for any precision assembly work.

Finally found 316 stainless screws that don't rust in my marine jigs – these M4 flat heads seat perfectly and the hex socket doesn't strip.
