M8×12mm 錐端止付螺絲 | 合金鋼 (250個/包)

The hex socket drive grabbed my Allen key securely even in a cramped spot under the workbench, and all 250 seated cleanly without any stripped threads. Cone point bit into the steel firmly enough that I didn't need threadlocker for a vibration-prone bracket.

I needed set screws that could handle high torque in a tight motor mount, and the hex socket drive on these makes adjustments a breeze. The alloy steel feels solid enough for repeated use, and the 250-count pack gives me plenty of spares for future projects.

The cone point on these M8 screws bites perfectly into the shaft, holding tight even under heavy vibration. All 250 pieces came cleanly threaded with no burs.
