براغي رأس أسطوانية M5-0.8 X 10mm | رأس مسطح محرك سداسي داخلي | ملولبة بالكامل | فولاذ مقاوم للصدأ 316 (600/عبوة)

Finally, a batch of bolts where every single one threaded smoothly without binding. The hex socket drive grabbed firmly on first try, saving me time on a jig build. Nice to get a full 600 pack that's actually consistent.

Used these for a marine railing repair where corrosion resistance was critical, and the 316 stainless held up perfectly after months in salt spray. The fully threaded length gave me solid grip in tight aluminum brackets.

Installed these in a saltwater environment and the 316 stainless is holding up perfectly so far. The hex drive seated cleanly without stripping, and having 600 pieces means I’m set for all my jig builds.
