M10 x 15mm 杯端內六角止付螺絲 | 合金鋼鍍鋅 (250個/包)

Half the box went into a fixture I’m building, and the hex socket drive made torquing them down in a cramped corner way easier than I expected. The zinc plating looks clean and none of them have stripped yet, which is more than I can say for cheaper packs.

The cup point really bites into softer metals without slipping, which is exactly what I needed for a gear hub lockup. A full box of 250 for this price feels like a steal, and the zinc finish hasn't shown a speck of rust after a week in a damp workshop.

The hex socket drive on these screws lets me really crank down without stripping the head in tight spots. Cup point tip seats flush perfectly against the metal surface every time. Pack of 250 was more than enough for my project, and the zinc plating hasn't chipped at all.
