براغي رأس سداسي ثقيل 1-1/8-7 × 3-1/2 بوصة | ستانلس ستيل 316 | كامل الخيوط (2/عبوة)

Used these on a saltwater equipment trailer, and the 316 stainless steel is showing no signs of rust after a few weeks of rain and road grime. The threads cut smoothly into the pre-tapped holes without any binding.

Installed these on a marine railing last week and the 316 stainless is already proving itself against the salt spray. The fully threaded length made it easy to get a solid bite into the wood.

The threading is clean and precise, so these cap screws seated perfectly without binding. I used them on a dock repair and the 316 stainless already feels more corrosion-resistant than the old 304s.
