براغي ذات نقطة مسطحة مقاس 1/4-20 × 1-3/4 بوصة من الفولاذ السبائكي (100/عبوة)

I needed longer set screws for a jig I’m building, and the 1-3/4" length was perfect for reaching through thicker material. The flat point holds firmly without marking up the surface.

These set screws are perfect for reaching that awkward threaded hole deep inside my jig's frame where a standard grub screw just won't go. The hex drive bit seated firmly and the flat point gave me a solid hold without marring the shaft.

I needed a full 1-3/4" length for a tight alignment jig, and the hex socket let me torque them down without stripping. The flat point seated squarely against the steel plate.
