براغي رأس سداسي M30-3.5 × 140 مم | فولاذ مقاوم للصدأ 316 | ملولبة بالكامل (5 / عبوة)

The 316 stainless steel is exactly what I needed for outdoor equipment that sees constant moisture. These hex heads grip the socket perfectly without any wobble, and the full threading makes alignment a breeze on my assembly jig.

Pulled my old machine's bolts out and replaced them with these 140mm hex heads—the 316 stainless feels solid and the threads ran clean the whole way down. Fit the socket perfectly, no slippage on the wrench.

These fully threaded 316s are the real deal for marine gear; the hex heads grabbed my socket cleanly and the 140mm length was perfect for my winch mount. Threading them in felt smooth with no galling on the stainless, and the pack of five covered my project with one spare.
