M16 X 80mm مسامير ضبط بنقطة كأس | فولاذ سبائكي (25 / عبوة)

The hex drive grabbed my allen key perfectly on a tight engine mount bolt, no stripping at all. These M16s felt solid and the cup point seated flush against the metal frame. Exactly what I needed for a heavy-duty attachment point.

Installed these on a heavy-duty jig and the cup point really digs in tight—no slipping at all. The hex drive made it easy to get full torque in a cramped spot. Exactly what I needed for a secure hold.

The hex socket drive handled my high-torque adjustment without stripping—solid bite. Only gave 4 stars because the 25-pack felt slightly overpriced for what's essentially fasteners.
