The perfect length for securing a heavy jig plate on my drill press, and the black oxide finish gives them a nice, corrosion-resistant look. Threads cut cleanly and the hex socket seated my driver without any wobble. Exactly what precision assembly work requires.

Putting together a custom jig for some repeat drilling, and these bolts were the perfect length. The black oxide finish gives them a nice, uniform look and feels durable out of the box.

Used these M14-1.5×55mm socket head screws to build a heavy-duty jig, and the hex socket drive made torquing them down in tight spaces effortless. The fully threaded shaft grabbed perfectly in my steel plate, and at 12.9 grade, they didn't strip under high load.
