براغي ضبط سداسية بنقطة كوب #1/4-28 × 7/16 بوصة | سبيكة فولاذ مطلي بالزنك (500/عبوة)

I was worried about stripping the hex socket on such small set screws, but they held up fine under a solid amount of torque with my hex key. The cup point bit into the shaft nicely for a secure hold.

Every single screw in the box threaded cleanly into my fixture with zero binding, and the hex socket held torque perfectly in the tight spot I couldn't reach with a wrench. The zinc plating already seems tougher than cheap hardware I've used before, so I'm set for a long time with these.

The hex socket drive grabbed perfectly with my wrench, and the cup point bit into the shaft without slipping. For a small part, these feel surprisingly sturdy—zinc plating should keep them rust-free in my damp garage.
