براغي رأس سداسي 7/16-20 × 6" | فولاذ درجة 5 زنك أصفر | ملولبة جزئيًا (25 / عبوة)

The hex heads grab my socket perfectly without slipping, and the yellow zinc coating on these grade 5 screws looks clean and durable. Used a few to replace worn bolts on a press—they threaded in smooth and held tight. Exactly what I needed for heavy equipment.

The partial threading on these 7/16-20 bolts made alignment in my equipment frame so much easier, and the hex heads grabbed cleanly with a socket every time. Grade 5 strength feels solid for the money, and the yellow zinc finish has held up without a hint of rust after a few damp weeks in the shop.

The yellow zinc coating on these looks even better in person, and the partial thread made cinching down my equipment bracket a breeze. Grade 5 is plenty stout for what I’m doing, and all 25 arrived clean with no burrs on the threads.
