براغي تثبيت سداسية برأس مخروطي محزز مقاس 3/8-16 × 1-3/4 إنش | سبائك فولاذية (100 / عبوة)

I needed set screws that wouldn't strip under heavy torque, and the hex socket drive on these made tightening in a tight spot much easier than I expected. The alloy steel feels really solid in hand, and the price for 100 pieces is a steal for my ongoing projects.

The knurled cup point really bites into soft metal without damaging the threads—I’ve had zero slippage on a few critical machinery adjustments. These 3/8-16 screws are also long enough to reach through stacked brackets. Exactly what I needed for high-torque applications.

Was a little worried about the fit on a custom fixture, but the hex socket drive made it easy to tighten even in the tight spot I needed. The knurled cup point really digs in nicely without slipping.
