M20-1.5 x 75mm 육각 머리 캡 나사 | 8.8급 강철 아연 도금 | 부분 나사산 (20개/팩)

Finally got these to bolt a steel beam onto a heavy press, and the zinc plating is holding up well with no rust after a week of shop use. The hex head grips perfectly with a socket wrench, and the partial threading made alignment much easier than I expected.

The partial thread on these M20 bolts made mounting my equipment frame a breeze since the smooth section aligned perfectly with the bushing. They're solid and the zinc coating looks clean—no rust concerns so far after a few weeks.

The partially threaded design made aligning these in my press jig much easier than fully threaded bolts. They seated perfectly with a standard socket and feel solidly built.
