5/8-11 X 1-1/2" 尼龍粒杯點止付螺絲 | 合金鋼 (50 顆/包)

The hex socket drive made snugging these into tight spots under the mill table way easier than I expected, and the nylon pellet grips the shaft without marring it. All 50 arrived clean and threaded true, so I've already got spares for the next job.

Used one to lock down a jig on my mill and the nylon pellet actually held the workpiece without marring it, which is exactly why I bought these. The cup point bites deep enough that there's no slipping, even at high torque. For fifty of these, the alloy steel feels solid and I've already reordered.

Used these for a heavy-duty jig on a press brake, and the hex socket made tightening in a cramped spot much easier. The nylon pellet really holds without marring the shaft.
