براغي رأس سداسية مجوفة بنقطة كوب M16 × 70 مم | فولاذ سبائكي (25 / عبوة)

Installed these M16 set screws to lock a pulley on a heavy shaft, and the hex socket drive made tightening in the tight spot surprisingly easy. The alloy steel feels plenty tough for the job, and the full 70mm length gave solid bite.

The cup point on these M16 set screws really bites in and holds firm, even in a vibrating machine base. The hex socket took my torque wrench without stripping, which is exactly what I needed for a precise alignment job. Glad I grabbed the 25-pack for spares.

I needed a longer screw for a specific fixture and these M16 x 70mm cup point screws were exactly what I was looking for. The alloy steel feels solid and the hex drive let me get them cinched down tight without any cam-out.
