براغي رأس سداسية ثقيلة 3/4-10 × 1-3/4 بوصة | ASTM A193 B7 فولاذ سبائكي عادي | ملولبة بالكامل (110 / عبوة)

I needed these for a heavy-duty press rebuild and the 3/4-10 threads engaged perfectly without any galling. The alloy steel feels solid in hand, and the plain finish cleaned up fast with a little degreaser.

The threads cut cleanly and the hex head seated perfectly with a standard wrench, so the full threading made alignment a breeze. I grabbed these for a general equipment rebuild and they're holding up exactly as the B7 alloy suggests.

I used these to bolt down a heavy press at the shop, and the hex heads gave my socket a solid grip without any stripping. The threads ran smoothly into the tapped holes, and the black oxide finish hasn't shown any rust after a month in a humid environment.
