1-1/2-12 X 6" 六角頭螺絲 | 美國製造 | 合金鋼 L9 黃鋅 | 部分螺紋 (5 / 包)

These are perfect for rebuilding a press at the shop. The partially threaded shank gave just the right grip depth, and the hex heads took a socket without any slipping.

The threads are clean and the yellow zinc finish looks consistent across all five bolts. I used them to secure a heavy equipment mount and they drove in smoothly with a socket, no binding at all.

Finally, some fasteners that don’t strip or wobble when I’m torquing them down on the press. The yellow zinc finish has held up nicely after a few days of shop use, and the partial thread gives just the right grip for the joint.
