براغي سوكيت سيت بمقبس بلاستيكي 3/8-24 × 5/8" برأس كوب نايلون | فولاذ سبائكي (100 / عبوة)

I needed set screws that could tighten down on a delicate shaft without marring it, and these nylon pellet cup points did the job perfectly. The hex socket drive let me get them snug even in a cramped spot on my lathe.

Used a dozen of these to secure a jig fixture on my mill table, and the nylon pellet bites nicely without marring the clamped surface. The alloy steel feels solid, and the hex drive holds up well under repeated tightening. Exactly what I needed for repeatable setups.

The hex socket drive made installing these in a cramped machine frame a breeze, and the nylon pellet tip holds firmly without damaging the shaft. For the price, you get a hundred solid set screws that feel well-made.
