براغي ضبط رأس كوب مقاس 7/16-20 × 7/8 بوصة | فولاد سبائكي (100 / عبوة)

The cup point bit into the shaft firmly without slipping, and the hex socket let me torque them down easily in a cramped bracket. For the price, getting a full hundred of these alloy steel screws felt like a steal.

I needed a solid batch for a jig I was building, and these set screws bite into the shaft perfectly with that cup point tip. The alloy steel feels tough, and the hex drive didn't strip even with a lot of torque.

The hex socket drive made tightening these in a cramped spot way easier than I expected, and all 100 threads spun on clean without a single burr. The alloy steel feels solid enough that I'm not worried about them stripping under load.
