1/2-13 × 6" براغي رأس سداسي | فولاذ درجة 5 أصفر زنك | خيط جزئي (25 / عبوة)

These 1/2-13 x 6" bolts fit perfectly into my milling machine, and the hex head makes tightening with a socket wrench quick. The partial threading is exactly what I needed for a strong hold without bottoming out.

The yellow zinc coating on these bolts seems tougher than the plain ones I usually grab; they drove into the steel bracket without any galling. Just the right length for a thick flange assembly I was working on.

Had to rebuild a piece of farm equipment and these grade 5 bolts held up perfectly under torque—no snapping or stripping. The partial threading made alignment in the mounting bracket so much easier than fully threaded alternatives.
