براغي رأس مقبس M4-0.7 × 14 مم | رأس مسطح محرك سداسي | ملولبة بالكامل | فولاذ مقاوم للصدأ 316 (600/عبوة)

Installed these in a jig I'm building and the 316 stainless is holding up perfectly against the coolant spray. The flat head sits flush just as expected.

I replaced the old zinc-plated screws on my precision jig with these 316 stainless ones, and they fit the hex socket perfectly without any stripping. The fully threaded grip is noticeably tighter, which should hold up better against corrosion in my damp workshop.

The hex socket drive makes these really easy to get a solid grip on, even in tight spots. I was surprised how cleanly the flat head sits flush once they're driven in. Just finished a jig build with them and the 316 stainless feels reassuringly tough.
