M3 x 25mm 平端內六角止付螺絲 | 合金鋼 (250顆/包)

For a recent project requiring precise locking adjustments in tight spots, the hex socket drive on these M3 set screws made installation a breeze. The 250-pack means I have plenty left for future builds too.

Used a full box of these on a jig build and not a single one stripped during tightening. The flat point seats nicely into the shaft and the hex drive bites deep enough that you can really crank them down in tight spots.

The hex socket drive on these M3s made torquing them down in a cramped bracket a breeze, and the flat point seated perfectly without wandering. All 250 arrived clean and uniform, threading smoothly every time. Solid value for the price.
