براغي تثبيت بمقبس سداسي برأس مخروطي مقاس 1/4-20 × 1-3/4 بوصة | فولاذ سبائكي (100 / عبوة)

The cone point bites into the shaft perfectly, and the hex socket lets you really crank them down without stripping. These 1-3/4" lengths are just right where a shorter screw won't reach.

Picked up a pack for some steel framing where space was tight—the hex socket drive let me get full torque with my socket wrench in corners a driver never would've fit. These cone point screws started cleanly in pre-drilled holes, and the alloy steel feels solid through and through.

Needed a cone point set screw to lock a pulley collar in place and these 1/4-20s went in smooth—the hex socket let me torque them down tight in a cramped spot without stripping.
