M5-0.8 x 130mm 소켓 캡 나사 | 육각 소켓 드라이브 | 부분 나사산 | 클래스 12.9 합금강 열처리 블랙 옥사이드 (100개/팩)

Needed a 130mm length for a deep jig assembly and these fit perfectly. The hex socket drive engaged cleanly without stripping, and the black oxide finish seems durable.

The black oxide finish on these M5s is exactly what I needed for a jig build—no glare under the work lights, and they thread cleanly into the fixture. The 100-count box is generous for prototyping, and the 12.9 alloy steel feels reassuringly solid compared to the 8.8s I've used before.

The hex socket drive seated perfectly with my Allen key, no rounding or stripping even at full torque. The thermal black oxide finish feels smooth and the 12.9 alloy steel is clearly built for heavy jig work, not cheap hardware.
