M5 X 16mm コーンポイント六角穴付き止めねじ | 合金鋼（250本/袋）

Cone point tip seats perfectly in the pilot hole, and the alloy steel feels sturdy enough to handle repeated adjustments without stripping. Exactly what I needed for a tight machinery fix.

The hex socket drive grabbed my Allen key with zero wobble, and the cone point centered itself cleanly in the pilot hole. All 250 screws came threaded consistently and none had burs or coating flaking off. Good value for a bag of solid hardware.

The cone point seated perfectly into the pilot hole without any wobble, and the hex socket held the driver firmly even at an awkward angle. For 250 pieces at this price, the alloy steel feels plenty tough for my jig setup.
