M16×25mm コーンポイント 六角穴付き止めねじ | 合金鋼 (100本/袋)

The cone point seats perfectly into the dimple on my shaft, and the hex socket lets me torque it down properly without stripping. For a hundred of these alloy steel screws, the price is hard to beat and they all arrived clean and threaded true.

I needed to secure a heavy-duty metal bracket in a tight corner, and these cone-point screws grabbed perfectly without needing a pilot hole. The hex socket held the driver firmly even at high torque, making the whole job much smoother.

The cone point bites in nicely for locking adjustments, and the hex socket handles decent torque without stripping. Only gripe is the bag could be sturdier for storage, but the steel itself feels solid for the price.
