M6-1 X 10mm 內六角螺絲 | 平頭內六角驅動 | 全螺紋 | 18/8不鏽鋼 (600入/包)

Ended up ordering these for a small repair job and was pleasantly surprised by the packaging—all 600 arrived neatly organized, no bent threads. The 18/8 stainless finish looks clean and the hex socket drive grabs the Allen key securely, even after repeated installs. Solid choice for the price.

The hex socket drive grips perfectly without stripping, which is a relief for a fastidious builder. These 600-piece packs are a solid value for machinery work.

Finally, a socket cap screw that actually fits tight without stripping the hex drive. Used a bunch of these on a jig rebuild, and the 18/8 stainless feels solid and corrosion-resistant. The flat head sits flush too, which saved me from reaming out counterbores.
