براغي تثبيت بنقطة كوب M16 X 40mm | فولاذ سبائكي (50/عبوة)

The hex socket drive made tightening these set screws in my machinery’s blind holes feel rock-solid, and the alloy steel finish is reassuringly tough. They threaded cleanly without any binding.

I was worried about stripping the heads in tight spots, but the cup point tip seated perfectly on my bracket assembly. These M16 screws have a solid bite and the hex drive handled every bit of the torque I needed.

The hex socket drive made torquing these down in a cramped spot way easier than I expected—no stripped heads or slipping. Cup point grips the shaft firmly once seated, and all 50 arrived clean with consistent threads. Solid buy for the price.
