M16×16mm 錐形點六角頭螺絲 | 合金鋼 (100入/包)

The cone point bites into the shaft really well—no slipping even under heavy vibration. All 100 screws arrived clean with sharp threads, and the hex socket drive made seating them in tight spots a breeze.

Used these to secure a heavy pulley bracket to a steel beam, and the cone point bit into the metal perfectly without slipping. The hex socket drive made tightening in the tight corner a breeze, and all 100 screws came with clean threads. Exactly what I needed for a solid, vibration-proof hold.

The cone point tip really helps these screws grab cleanly into the metal, and the hex socket drive lets me apply good torque without stripping. Worked perfectly for mounting some brackets in tight spots.
