M8 X 8mm 杯頭內六角止付螺絲 | 18/8 不鏽鋼 (500 顆/包)

Finally, a set screw that digs in properly when torqued down—the cup point actually bites into the shaft. The hex socket drive makes adjustments in tight spots much easier than a slotted head would.

I've been using these M8 cup point screws for mounting brackets on my workbench, and the hex socket drive lets me get them snug even in awkward corners without stripping. The 18/8 stainless steel finish looks clean and hasn't shown any rust after a few weeks in my damp garage.

Installed these in a metal jig I'm building and the hex socket drive gives a great grip for tightening them down in tight spots. The 18/8 stainless steel feels solid, and having a full 500 pack means I won't run out midway through. Exactly what I needed for precise, permanent adjustments.
