M12 X 90mm 杯端止付螺絲 | 合金鋼 (50 / 包)

Used these to secure a heavy jig on my mill table, and the cup point bites down without slipping. The alloy steel feels tough enough for repeated adjustments. Exactly what I needed for a firm hold in tight spots.

The hex socket drive made torquing these down in a cramped corner way easier than fumbling with a wrench. All 50 pieces have clean threads and the cup point tip bites firmly without stripping. Worked perfectly for my jig build.

Installed these in a tight engine bay and the hex socket drive let me torque them properly without stripping. The cup point tip also helps align them perfectly before final tightening.
