1-1/8-7 × 10" براغي رأس سداسي | صناعة أمريكية | درجة L9 فولاذ سبائكي زنك أصفر | خيوط جزئية (8 / عبوة)

The 1-1/8-7 threads on these are clean and uniform, so they drove in straight without any binding. The partially threaded design gave me just the right grip for the heavy equipment assembly I was working on, and the L9 alloy steel feels rock solid.

Used these to fasten a custom bracket to a heavy-duty frame, and the Grade L9 steel held torque perfectly without stripping. The partial threading made alignment much easier than fully threaded bolts would have.

Finally got these to replace a snapped bolt on our press brake and the partially threaded design made alignment way easier than I expected. The yellow zinc finish has held up fine against the hydraulic oil and grime in the shop, and the hex head grabbed the socket clean with zero stripping.
