M6-1 X 40mm 六角穴付きボルト | 低頭六角穴 | 半ねじ | 18/8 ステンレス鋼 (200本/パック)

Finally, a box of 200 screws where every single one threads cleanly into the jig without binding. The 18/8 stainless has a nice, smooth finish and the partially threaded section grips perfectly for my precision assembly work.

The low head profile fits perfectly where standard socket heads won’t clear, and the 18/8 stainless feels solid out of the box. I used them on a jig and they threaded in clean without any binding. Just wish the partial thread started a bit sooner, but for the price per piece, it’s a solid buy.

The packaging alone made this worth it—200 screws neatly sorted with no scratches or bent threads. The low head design fits flush in my jig where standard cap screws would have fouled, and the 18/8 stainless is holding up great in the shop.
