براغي ضبط مقبس بنقطة كروية مخددة 1/2-13 × 7/8 بوصة | فولاذ سبائكي (100/عبوة)

The hex socket drive made these easy to tighten in a tight spot, and the knurled cup point tip holds really well on the surface. I’ve used a dozen already and not one has stripped. Solid little screws for the price.

Installing these in a jig where space was tight—the hex socket drive made it so much easier than messing with a wrench. The knurled cup point bit into the shaft nicely. Exactly what I needed for a hundred pack.

The alloy steel on these set screws feels really durable, and the knurled cup point tip held tight without slipping during assembly. Perfect for getting into those cramped spots where a regular wrench just won't fit.
