3/4-10 X 1/2" 滾花杯點內六角止動螺絲 | 合金鋼 (100個/包)

The knurled cup point on these set screws really digs in and holds tight, which is exactly what I needed for a stubborn pulley application. All 100 pieces in the package had clean, uniform threads.

The hex socket drive made seating these in a tight spot way easier than I expected, and the alloy steel feels solid enough to trust under real torque. Pack of 100 means I’ve got plenty left over for the next job, and the knurled grip on the cup point holds its bite without stripping.

The knurled cup point gives these screws a nice grip when seating them, and the hex socket takes a standard Allen key without stripping. Worked perfectly for some delicate fixture adjustments where I needed a clean, flush finish.
