براغي رأس سداسي 1 بوصة-14 × 3-1/2 بوصة | فولاذ درجة 5 مع زنك أصفر | خيط جزئي (10 / عبوة)

The yellow zinc coating on these cap screws is nice and uniform, and the partial threading made installation into a pre-tapped hole much easier than fully threaded bolts. They seated snugly with a socket wrench and held up to torque without any stripping.

I needed these for heavy-duty machinery assembly, and the hex head gave a solid grip with my socket wrench, no stripping or slipping. The yellow zinc coating on these grade 5 screws seems durable, and the partially threaded length worked perfectly for clamping layers together.

Finally got around to replacing some worn bolts on my press, and these Grade 5 hex heads fit perfectly with a socket. The yellow zinc coating looks good and should resist rust in the shop.
