براغي رأس أسطوانية M6-1 × 50 مم | محرك سداسي | ملولبة جزئيًا | فولاذ سبائكي من الفئة 12.9 مطلي بالزنك (200 / عبوة)

I needed a batch of high-strength screws for a jig I was building, and these 12.9 alloy steel cap screws did the job perfectly. The zinc plating looks uniform and should resist rust in my shop, and the hex socket drive made installation a breeze with no stripping.

The partial threading on these M6 screws made them ideal for a jig I was building—they grab securely without bottoming out prematurely. Bag of 200 should last me through several projects, and the zinc plating looks clean and durable.

The hex drive bites perfectly without any cam-out, and the zinc plating looks uniform across all 200 pieces. I’ve used about 40 so far on a jig build, and every single one threaded in smooth with no seized or burred threads.
