براغي مقبس نقطة كأس كبسولة نايلون #5/16-24 × 1/2 بوصة | فولاذ سبائكي (100/عبوة)

The nylon pellet tips held fast even on a slightly worn shaft, which surprised me. For the price, getting 100 of these with the hex socket drive feels like a solid deal.

The hex socket drive made seating these in a tight spot incredibly easy, and the nylon pellet cup point grips the shaft firmly without marring it. For the price per hundred, these are a solid value for any jig or fixture build.

I was worried the nylon pellet might deform under pressure, but these alloy steel set screws held perfectly when I adjusted a jig fixture. The cup point really digs in securely without marring the shaft.
