M6-1 X 12mm 육각 머리 나사 | 8.8급 강철 아연 도금 | 풀 나사산 (800개/팩)

The zinc coating is consistent across all 800 pieces, and the threads are clean enough that they’ve driven into my steel frames without any binding. For the price per unit, I’m stocked up for a couple of years of builds—these feel properly hardened, not the cheap stuff you sometimes get in bulk.

The hex head on these M6 bolts grips perfectly with a socket, making assembly on my equipment frame much faster. At 12mm length they're exactly what I needed for the bracket mounts, and the zinc plating looks clean. Pack of 800 should last me through several projects.

I used these to secure brackets on a small machine build, and the fully threaded shafts grabbed evenly with no stripping. The hex heads held a socket wrench nicely without slipping under torque, and the zinc plating keeps them rust-free in my damp shop. Exactly what I needed for the price.
