M14 x 40mm 杯形點內六角螺絲 | 合金鋼 (50 個/包)

I needed a hard-to-find M14 set screw for a machine repair, and these 40mm alloy steel ones fit the bill perfectly. The cup point bit into the shaft securely without slipping.

The hex socket drive made torquing these down in a cramped machine frame a breeze – no fumbling with a wrench. Cup point bites into the shaft firmly, and the alloy steel feels tough enough for repeated adjustments.

I needed to get a good grip in a tight engine bay, and these M14 cup point screws let me crank them down with my hex key without stripping. The alloy steel feels solid and the 40mm length was exactly what the bracket required.
