براغي سوكيت نقطة كوب مع رقعة نايلون 3/8-24 × 1-1/4 بوصة | فولاذ سبائكي (100 / عبوة)

The nylon patch on these set screws held fast during a high-vibration application where standard fasteners kept loosening. The hex socket made installation in that tight spot a breeze. Exactly what I needed for a precise locking adjustment.

I was pleasantly surprised by how easily these drove into the steel frame, thanks to the hex socket drive in that tight corner. The cup point tip gives a nice, clean finish that’s perfect for my project.

The nylon patch really locks them in place—I tightened a few on a jig last week and they haven't budged since. That hex socket drive made it easy to get them snug in a tight spot without stripping.
