براغي رأس كوب مقبس 3/8-16 × 1-5/8 بوصة | سبائك فولاذ (100 / عبوة)

The hex socket drive made installing these in a tight machinery spot much easier than I expected. The alloy steel feels sturdy, and the cup point tip seated perfectly against the surface.

Finally got these installed on a piece of machinery where the old screws kept stripping; the hex socket drive grabbed tight even in a tight spot. The cup point tip really digs in and holds, which is exactly what I needed for a permanent fix.

I needed set screws that could handle repeated adjustments in confined areas, and the hex socket drive on these has been a real time-saver. The cup point tip dug in cleanly on the first try, and the alloy steel feels solid enough for heavy use.
