براغي مسطحة الرأس #6-40 × 1/2 بوصة من الفولاذ السبائكي (250/عبوة)

The flat point tip is perfect for flush-mounting without marring surfaces, and the alloy steel feels solid. I used a full package for a jig build and every screw threaded without a hitch.

The hex socket drive made torquing these down in a tight spot on a jig much easier than with a standard slotted screw. Nice that the flat point helps them sit flush without chewing up the surface. Solid little fasteners for the price.

I've been using these set screws for some small jigs and the alloy steel really holds its torque well without stripping. The flat point seats nicely against curved surfaces too.
