M16 X 80mm 平頭內六角螺絲 | 合金鋼 (25入/包)

Used these to secure a heavy-duty jig in a tight spot on my milling table, and the flat point gripped perfectly without marring the surface. The alloy steel feels solid and the 80mm length gave me just enough engagement. Worked exactly as needed for precise positioning.

The hex socket drive really lets you crank these down tight without stripping; I used them for mounting heavy-duty brackets and they held perfectly. The flat point tip made alignment in a recessed hole effortless, and the alloy steel feels solid. Exactly what I needed for that high-torque job.

These M16 flat point screws bite perfectly into my shaft, and the hex drive lets me really crank them down without stripping. The 80mm length gives plenty of thread engagement for my heavier gear.
