براغي رأس سداسية مقاس 1"-8 × 6-1/2" | فولاذ درجة 5 أصفر زنك | ملولبة جزئيًا (35/عبوة)

The partially threaded shaft made installation so much easier than fully threaded bolts, and the hex head gripped my socket perfectly. These Grade 5 screws feel rock solid for heavy equipment assembly.

Had to replace some bolts on a heavy press and these grade 5 screws held up perfectly under torque. The hex head gave my socket wrench a solid grip, and the yellow zinc finish seems tough enough to resist rust in the shop.

The partial threads make these perfect for bolting heavy equipment together without binding. All 35 screws arrived with clean threads and consistent plating, exactly what I needed for my press rebuild.
