براغي رأس سداسية مقاس 1"-14 × 3-1/2" | صناعة أمريكية | درجة L9 سبيكة فولاذية صفراء زنك | ملولبة جزئيًا (10/عبوة)

Had to torque these to spec on a heavy equipment repair, and the hex head held up perfectly with a socket wrench. The partial threading made alignment a lot easier than fully threaded bolts I've used before.

Yellow zinc finish looks sharp and the partial threads made cinching down on a thick flange much easier than fully threaded bolts. These hefty 3.5-inch L9s torqued up smoothly with a socket and haven’t loosened a bit under vibration.

Used these to secure a heavy press at the shop, and the partial threading made alignment in tight spots much easier. The hex heads grabbed cleanly with a socket and didn't strip.
