M4 x 8mm 평면 끝 세트 스크류 | 18/8 스테인리스 스틸 (1000개/팩)

Finally got around to rebuilding a precision clamp and these M4 flat point screws fit perfectly in the tight hex socket. The stainless finish feels solid and should resist rust in my workshop.

Used these to dial in a jig fixture where a regular hex head wouldn’t fit—the socket drive grabbed perfectly with a ball-end wrench, and the 18/8 steel held up fine under repeated torque. Nice to have a full thousand pack for about the same price I’d pay for a hundred elsewhere.

After struggling with cheap set screws stripping out on my bike’s derailleur, the hex socket drive on these gives me way more grip, and the 18/8 stainless steel feels solid enough that I doubt they’ll rust.
