M12 x 35mm 錐頭止付螺絲 | 合金鋼 (100顆/包)

The cone point seated perfectly into the center mark on my shaft, so no walking or slipping during the high-torque adjustment. The alloy steel feels solid, and all 100 threaded cleanly with no burrs or defects. These are exactly what I needed for a tight spot where a wrench wouldn't fit.

The hex socket drive made tightening these into a tight spot on my jig super easy without stripping. The alloy steel feels really solid for the price, and the cone point centers perfectly.

Installing these on a conveyor roller assembly was a breeze—the hex drive gripped perfectly in a tight spot. The cone point seats firmly without walking, and the alloy steel feels tough enough for repeated adjustments.
