M6-1 X 14mm 六角頭螺絲 | 316 不鏽鋼 | 全螺紋 (300 / 包)

The threading is clean and uniform across all 300 pieces—no burs or stripped heads out of the box. I've used them for a few equipment mounts and the 316 stainless finish feels properly marine-grade, though the pack is heavier than I expected for its size.

Finally got around to using these for a new outdoor equipment build, and the fully threaded length made tightening into a steel bracket much easier than my usual half-threaded screws. The hex head gave a solid grip with a socket, no stripping.

These 316 stainless screws are exactly what I needed for a boat railing repair, and the fully threaded length let me get a solid bite into the mounting bracket. The hex heads drive smoothly without stripping, and 300 in one pack is plenty for future projects.
