براغي ضبط بنقطة كوب M16 × 55 مم | سبائك الصلب (25 / عبوة)

I used these to secure a custom jig I built, and the cup point really digs in to prevent any loosening under vibration. The hex socket lets me get them tight in a cramped spot without camming out.

After my factory press kept vibrating loose, these set screws with the cup point tip finally held the collar in place. The hex socket drive made torquing them down in that cramped spot far easier than I expected.

The cup point grips the shaft firmly without marring it, which is exactly what I needed for a stubborn pulley. The hex socket drive made torquing these down in a cramped spot way easier than a plain Allen head. Solid 25-piece pack for the price.
