براغي رأس كوب نقطة 7/8-9 × 3-1/2 بوصة | فولاذ سبائك (10 / عبوة)

These things are beefy at 7/8-9 thread; the hex socket held up fine when I really torqued them down in a tight spot. The cup point dug in exactly as it should to lock the collar in place.

The cup point tip on these screws grabbed perfectly and held firm when I was adjusting a tight jig on my workbench. They drove in smoothly with a hex key and the alloy steel feels solid. Just what I needed for that project.

I was a little nervous about the hex socket drive stripping under high torque, but these held up perfectly when I adjusted a heavy-duty coupling. The cup point tip really digs in.
