M20 X 80mm 平先六角穴付き止めねじ | 合金鋼 (10 / パック)

These M20 bolts fit perfectly into the heavy-duty jig I'm rebuilding, and the hex socket drive made it easy to get them snug even in a cramped corner. The flat point tip seated cleanly without any frustrating wobble during installation.

Had to tighten a loose machine guard in a tight spot, and the hex socket drive made it easy to get the torque I needed with a standard Allen key. The flat point pressed firmly into the mating surface without slipping. Solid alloy steel feel, too.

Finally, set screws that actually bite into the shaft without rounding out; the hex socket drive gives you plenty of torque even in tight spots. The alloy steel feels incredibly sturdy for the price.
