1/2" X 4 3/4" ソケットショルダーボルト | ソケットヘッド | ソケットドライブ | 合金鋼 (25個/パック)

Finally, a shoulder screw that actually fits the bearing without any slop. The hex socket drive made torquing them down a breeze, and alloy steel gives me confidence they'll hold up on the milling machine.

The precision-ground shoulder on these is flawless, no burs or wobble when I spin them as an axle in my jig. They seated cleanly in the hex socket and held up under some serious side load without a hint of play. Exactly what I needed for a permanent pivot point.

I needed some strong pivots for a small mechanical project, and these screws fit perfectly in the 1/2" bore without any wobble. The hex drive made installation quick, and the alloy steel feels solid enough for repeated use.
