براغي تثبيت من النايلون برأس كروي مقاس #4-40 × 1/4 بوصة | فولاذ سبائكي (100/عبوة)

I needed set screws for a tight space in a jig I was building, and the hex socket drive made installation a breeze even with limited clearance. The nylon pellet seems well-seated and the cup point held firm during a quick test fit. Great value for a hundred pack.

The cup point bit into the steel exactly where I needed it, and the nylon pellet held firm under vibration. For a hundred pieces at this price, the alloy steel feels solid, and the hex socket gave me plenty of torque without stripping.

The hex socket drive made tightening these in a cramped spot way easier than I expected for such a small screw. The nylon pellet tip held firm once seated, and a hundred pieces for the price feels like a solid deal.
