براغي تثبيت سداسية M4 × 8 مم بنقطة كلب كاملة | فولاذ سبائكي (500 / عبوة)

I used these to secure a gear shift linkage on my motorcycle, and the hex socket drive made tightening in that cramped space much easier than I expected. The alloy steel feels tough and should handle the vibration just fine.

The full dog point tip seated perfectly in the steel bracket I was repairing, and the hex drive let me torque it down without any cam-out. For the price, getting 500 of these in alloy steel feels like a steal.

I was a bit skeptical about buying a bulk pack of set screws, but these M4 x 8mm ones with the hex socket drive work perfectly in my jig. The dog point tip really locks into the dimple without slipping.
