براغي رأس سداسي ثقيل 3/4-10 × 3-1/4" | صنع في الولايات المتحدة | فولاذ درجة A307 مطلي بالزنك | جزئي الخيوط (75/عبوة)

Tackling a big equipment assembly project, I was impressed these 3/4-10 x 3-1/4" hex screws drove in smoothly without any binding. The zinc plating gave them a clean, consistent finish, and having 75 per package meant I didn't run short.

These 3/4-10 x 3-1/4" heavy hex cap screws threaded perfectly into my equipment frame without any binding. The A307 Grade B steel feels solid and the partial threading made installation quicker than fully threaded bolts.

The zinc coating on these bolts is smooth and even, no flaking like cheaper hardware. Threads cut clean into the nut, and the partially threaded design is perfect for my trailer hitch build.
