3/4-16 X 6" 六角頭螺絲 | 美國製造 | L9級合金鋼黃鋅 | 部分螺紋 (20個/包)

I needed some heavy-duty bolts for a farm equipment repair, and these L9 alloy steel cap screws fit the bill perfectly. The hex head let me get a solid socket grip without any rounding, and the partial threading made alignment a breeze.

Finally a fastener that doesn’t strip or snap under heavy torque—the yellow zinc coating held up fine during assembly, and the partial threading made alignment on my press frame much easier. These are exactly what I needed for a repair job requiring serious tensile strength.

These bolts fit the hydraulic press I'm rebuilding with zero slop. The yellow zinc coating is already holding up better than the black oxide ones I used before.
