براغي رأس كبسول 5/16-18 × 7/8 بوصة | محرك سداسي رأس زر | ملولبة بالكامل | فولاذ ستانلس ستيل 316 (200/عبوة)

Used a handful to mount brackets for a marine railing system, and the hex socket drive made installation much faster than slot-head screws I've had to deal with before. The 316 stainless has held up perfectly so far in a saltwater environment with no signs of corrosion.

I've been using these for a few weeks on a custom jig, and the 316 stainless finish has held up perfectly in my shop's humid environment. The hex socket drive seats cleanly with no stripping, and the thread engagement on the 7/8" length feels solid.

These button head screws were exactly the right length for a jig I'm building, and the 316 stainless feels reassuringly solid. The hex socket drive made them easy to install with my Allen key.
