براغي تثبيت برأس مخروطية مقاس 1/4-28 × 1-1/4 بوصة | فولاذ سبائكي (100 / عبوة)

I’ve been using these for a couple of small assembly projects, and the cone point really helps get a clean start in tight spots without stripping. The hex socket holds firm even when I’m torquing them down with a driver in a cramped space. Definitely my go-to for that 1/4-28 size now.

The hex socket holds the driver perfectly even when I'm adjusting these in a tight spot on a jig. The cone point really grabs and centers the workpiece, and the alloy steel feels plenty strong for my application.

Finally a set screw that actually stays put once torqued down. The cone point bites into the shaft perfectly without slipping.
