براغي رأس سداسي 1/4-20 × 6 بوصة | فولاذ درجة 5 زنك أصفر | ملولبة جزئيًا (50/عبوة)

The hex heads fit my socket driver perfectly, and the yellow zinc coating looks clean and durable. Used these to secure a metal stand in my workshop, and the partial threading made alignment much easier.

I needed longer bolts for a conveyor repair and these 6-inch partially threaded screws grabbed perfectly without bottoming out. The hex heads let me really torque them down without stripping.

The Grade 5 steel feels solid, and the yellow zinc coating on these 1/4-20 screws seems like it'll hold up well. They threaded cleanly into my equipment frame with no binding. A great, no-nonsense pack for industrial use.
