براغي مقبس نقطة مخروطية M4 X 5mm | سبيكة فولاذ (500/عبوة)

Picked up these for some tight adjustment work on a jig I’m building—the hex socket drive gives solid control without stripping. The cone point seated perfectly in the countersink.

Used a few of these to secure a small pulley onto a motor shaft, and the hex socket drive let me really crank them down in a cramped spot. The cone points bite into the shaft nicely without any slipping. Solid pack for the price.

I was worried the cone point might slip on my aluminum shaft, but it bites in perfectly and holds solid under vibration. The alloy steel feels tough, and the hex socket lets me get them snug in tight corners without stripping.
