براغي آلة سداسية 5/16-18 × 1-1/8 بوصة | فولاذ مقاوم للصدأ 18/8 | ملولبة جزئيًا (200 / عبوة)

Needed some stainless bolts for a marine project where corrosion resistance is key, and the 18/8 grade on these is exactly what I was after. The 1-1/8" length with that unthreaded grip portion lined up perfectly with the bracket thickness I'm working with.

The partially threaded shank gave me that solid grip length I needed for a snug fit through the frame and plate, and they held up fine outside in the rain for a week now. Pack of 200 is plenty, and the hex heads seated cleanly with a standard wrench without any stripping.

The stainless steel finish on these has held up great in a damp shed for two months now—no rust at all. The unthreaded shank made alignment a breeze when assembling a metal frame.
