براغي مقبس مخروطية M4 × 8 مم | فولاذ سبائكي (500 / عبوة)

The cone point seats perfectly into the shaft dimple, and the hex socket lets me torque them down snug without stripping. I've gone through maybe 40 of these for a jig build and not one has failed me. Exactly what I needed for the price.

The hex socket drive on these M4 set screws made installation in my machinery adjustments really easy, even in cramped spots. The alloy steel feels sturdy and the cone point grips well without slipping.

The cone point on these M4 set screws grips really well—I used them to secure a collar on a small shaft and they haven't budged. The hex socket drive makes them easy to tighten in a tight spot without stripping. Solid value for a 500-pack.
