M3 X 6mm 先端フラット六角穴付き止めねじ | 合金鋼 (1000本/パック)

The hex socket drive is what sold me—it grips the Allen key perfectly, so cinching these down in a tight spot isn’t a fight. Flat point tips seat cleanly without chewing up softer metals. All 1000 arrived rust-free and consistent.

Sorted through the whole bag and every single one has a clean, sharp hex socket drive—no stripped edges or burrs. They seat flush in my fixtures thanks to the flat point tip, which is exactly what I needed for precise positioning. At this price for a thousand, I’m set for years.

I needed a reliable set screw for a tight-spaced jig assembly, and these M3 flat points held firm after several adjustments. The hex socket drive made installation a breeze in awkward corners.
