براغي تثبيت بنقطة كوب 1/4-28 × 3/4 بوصة | فولاذ سبائكي مجلفن (250 / عبوة)

The hex socket drive made installing these into my milling machine's T-slots a breeze without stripping the head. Cup point grabs tight even under vibration, and the zinc plating has held up fine against minor coolant splashes so far.

I needed to secure a jig in a tight spot, and the cup point tip on these screws gripped perfectly without slipping. The zinc plating seems tough enough to resist rust in my shop, which is a nice bonus.

The hex socket drive made seating these in a tight spot way easier than I expected—no stripped heads, even with a stubby Allen key. The cup point bit into the shaft cleanly and they’ve stayed put through a few heavy cycles so far.
