براغي رأس سداسي ثقيل 1-1/4-7 × 3-1/2 بوصة | ستانلس ستيل 316 | ملولبة بالكامل (2/عبوة)

These are seriously beefy bolts. I needed them for attaching a heavy bracket to a steel beam, and the 316 stainless gives me peace of mind about corrosion in a damp environment.

I’ve been using these 316 stainless screws to replace rusted hardware on a saltwater dock, and after three weeks they still look perfect. The coarse 1-1/4-7 threads bit into the steel effortlessly without stripping. Off to buy another pack for the next repair.

These 316 stainless hex cap screws threaded cleanly into my marine hatch assembly without any binding. The fully threaded design gave me plenty of grip for a solid, lasting hold.
