براغي رأس سداسي M4-0.7 × 10 مم | فولاذ مقاوم للصدأ 316 | ملولبة بالكامل (500 / عبوة)

Finally got around to swapping out the rusty old bolts on the boat trailer, and these 316 stainless steel hex heads thread in so smoothly with a socket. Exactly the right M4-0.7 pitch I needed, and the 500-pack means I won't have to scramble for spares for a while.

Went through almost the whole bag replacing rusty fasteners on outdoor gear, and not a single one stripped during install. The 316 stainless is exactly what I needed for salt-air exposure, and the fully threaded length gives a solid grip in thin brackets.

The hex heads really bite into a socket without any stripping, and the 316 stainless finish has a clean, consistent look across all 500 pieces. I sorted through a handful and didn't find a single dud, threading was smooth every time.
