M2.5-0.45 X 5mm 소켓 캡 나사 | 접시머리 육각 소켓 드라이브 | 풀 나사산 | 클래스 12.9 합금강 아연 도금 (600 / 팩)

I needed some reliable M2.5 screws for a small jig I’m building, and the hex socket drive on these makes them easy to tighten without stripping. The 600-count pack was way more than I expected for the price, and the zinc plating looks clean and strong. Only wish they came in a resealable bag for sto

Finally, a flat head screw that actually sits flush on my 3D printer carriage. The 12.9 alloy steel feels noticeably tougher than the cheaper ones I've used, and the plating is even across the whole batch of 600.

The hex socket drive grabs the Allen key beautifully, and the zinc plating gives them a clean, consistent finish. I used a few to secure a small jig on my milling table, and they held up perfectly under vibration. For the price, getting 600 of these class 12.9 screws feels like a steal.
