M5 X 16mm 소켓 캡 나사 | 로우 헤드 육각 소켓 드라이브 | 클래스 8.8 합금강 (600/팩)

For the price of a decent lunch, I got a full box of 600 — and every single one threaded perfectly into my jig fixture without any burrs. The low head profile gave me just enough clearance under a tight bracket.

My torque wrench readings came out right on target with these, and the Class 8.8 alloy steel has held up through a full week of test runs on my jig. Having six hundred of them means I won't run out mid-project, which is honestly the best part.

I needed low-profile fasteners for a tight assembly project, and the hex socket drive made installation easy even in cramped spaces. The class 8.8 alloy steel feels robust for the price, though a few screws had slightly uneven threads. Still, they held well in my jig without stripping.
