M8 X 40mm 平點內六角止付螺絲 | 合金鋼 (100 顆/包)

Finally got around to replacing the seized adjuster on my mill's gibs — these M8 flat points bottomed out perfectly in the blind hole. The hex socket drive really lets you crank them down without stripping.

Used these to secure a jig fixture on my milling table and the flat point held perfectly without marring the surface. The alloy steel feels tough enough for repeated high-torque adjustments, and the 40mm length was just right for my setup.

The hex socket drive made installing these in a tight cabinet frame much easier than I expected. They threaded smoothly into the pilot holes without any binding. A solid pack for the price.
