مسامير ضبط نقطة كوب 7/16-14 × 3/8" | من سبيكة الصلب مطلي بالزنك (100/عبوة)

The cup point bit into the shaft firmly without slipping, and the zinc plating looks like it'll resist rust well. I used them for a jig I'm building and all 100 were cleanly threaded.

The hex socket drive made tightening these in a cramped bracket a breeze, no stripped heads or slipping. The zinc plating looks clean and uniform across all 100 pieces, and they held firm once I set them with a torque wrench. Exactly what I needed for the job.

The hex socket drive let me get these screws snug in a tight bracket without stripping the head. Zinc plating seems solid so far with no rust after a few weeks in a damp shop.
