M16 X 40mm براغي تثبيت برأس أسطوانية بنقطة مخروطية | فولاذ سبائكي (100/عبوة)

The cone point seated perfectly into the dimple on my shaft, and the alloy steel held up under heavy tightening without stripping the hex drive. Exactly what I needed for a precise locking application.

The hex socket drive grabbed the threads perfectly even in a tight spot where I couldn't get a regular wrench in. For a hundred pieces at this price, the alloy steel feels solid and the cone points are sharp right out of the box.

The cone point tip seated perfectly in the pilot hole without any walking, which I really appreciated for a clean start. They've held firm in my steel framing project without stripping.
