براغي مقبس نقطة كوب 3/8-16 × 3" | فولاذ سبائكي (100 / عبوة)

I needed some extra length for a stubborn adjustment, and these 3-inch screws gave me the reach to finally get it right. The hex socket drive held steady under some serious torque without stripping.

The cup point bites into the shaft like it’s supposed to, and even after cranking them down with a hex key, the threads on all 100 feel clean and uniform. Took a full afternoon to use most of a box on a jig and didn’t strip a single one.

I was worried that with the hex socket drive these would be tricky to tighten, but the high-torque adjustment made setting them super easy even in a cramped mounting bracket. The cup point tip digs in nicely to hold firm without slipping.
