Parafusos de cabeça cilíndrica com ponta plana M4 x 8 mm | Aço liga (1000 / Embalagem)

The hex socket drive made cinching these down in a cramped bracket a breeze, and the flat point seated firmly without walking. All 1000 in the bag, and every single one threaded clean on the first pass. Solid value for the price.

Used a full bag of these for a jig build and every single one seated cleanly without stripping. The flat point bites into the workpiece way better than a cup tip would, and the alloy steel held up to repeated tightening. At this price for a thousand, I'm stocked for years.

For a full box of a thousand, these M4 set screws are a solid deal—the hex socket makes tightening them in tight spots surprisingly easy. I used them to secure a small knob on a machinery jig, and the flat point held firm without damaging the shaft.
