مسامير مقبس ذات نقطة كوب M6 × 35 مم | فولاذ سبائكي (250 / عبوة)

I used these to secure a pulley on a go-kart, and the hex socket drive let me get full torque even in a cramped frame. The cup point bit firmly into the shaft without any slipping, which was exactly what I needed.

Installing these in a tight spot under the dash was a breeze thanks to the hex socket drive, and the cup point tip sits flush. The alloy steel feels solid, so I’ve got no worries about them stripping out. A solid 250-pack for the price.

These set screws gripped tight when I used them to lock a pulley onto a motor shaft; the hex drive let me torque them down properly in a cramped space. Build quality looks consistent throughout the whole bag, and the cup points left solid little bite marks on the shaft.
