M2 x 12mm 杯端內六角止付螺絲 | 18/8 不鏽鋼 (250 / 包)

The cup point bites into the shaft nicely without stripping, and the hex socket lets me torque them down in awkward spots on my CNC rig. 250 pieces in 18/8 stainless for this price means I won't run out mid-project.

These set screws fit perfectly in my 3D printer’s hotend mount, and the hex drive let me torque them down securely even in the cramped space. The 18/8 stainless feels solid and rust-resistant for the price.

Used these to lock down a couple of brass knobs on a small jig I'm building, and the hex socket drive made seating them in tight spots a breeze. The stainless steel feels solid, no stripping or rust after a few days.
