براغي مقبس كوب بلاستيك 3/8-24 X 1/2" | فولاذ سبائكي (100 / عبوة)

Bought these for a jig fixture where I needed a non-marring hold, and the nylon pellet tip worked perfectly to grip without scratching the aluminum surface. All 100 were consistent in threads and finish, and I torqued them down without any stripping.

The nylon pellet on the cup point grips the shaft without leaving a burr, which is exactly what I needed for a light-duty alignment job. A full hundred of them for the price feels like a steal, and the hex socket drove in smoothly even when I had to reach a tight spot.

These little nylon cup point screws held like a dream when I tightened them into a soft aluminum piece, and the hex socket drive made it easy to get them snug in a tight spot. Exactly what I needed for a quick adjustment job.
