براغي ضبط بنقطة كوب مع كرة نايلون 1/4-28 × 1/2 بوصة | فولاذ سبائكي (100/عبوة)

The hex socket drive made installation a breeze in a cramped machine corner—no stripped heads here. These alloy screws feel solid and the cup point tip seats perfectly flush. Exactly what I needed for precise adjustments.

I needed a set screw that wouldn't mar a delicate shaft, and the nylon pellet in the cup point worked perfectly for that. All 100 pieces look uniform, and the hex socket drove them in easily without any stripping.

The hex socket drive made cinching these down in a tight spot way easier than I expected, and the nylon pellet seats firmly without marking the shaft. I’ve used about thirty so far and not a single one has stripped or backed out.
