براغي رأس سداسي M6-1 × 45 مم | محرك سداسي داخلي | رأس مسطح | ملولب جزئيًا | فولاذ مقاوم للصدأ 316 (100/عبوة)

The 316 stainless finish is flawless on all 100 pieces, and the flat head sits perfectly flush in my precision assembly. Threading was smooth and consistent across the whole batch, which saved me a ton of setup time.

Used a handful to mount a custom jig on my milling table and the flat head sits flush perfectly with the countersink. The 316 stainless feels sturdy and the partial threads made alignment much easier than expected.

I was a bit nervous about the packaging surviving shipping, but every single screw arrived in perfect condition. The partially threaded design grabbed exactly where I needed it to in my jig, and the 316 stainless finish looks like it’ll laugh off moisture.
