براغي رأس سداسية داخلية M2.5-0.45 × 25مم | محرك سداسي | ملولبة بالكامل | فولاذ مقاوم للصدأ 316 (400 / عبوة)

Used a hundred of these to build a jig for a production run, and the 316 stainless held up perfectly in a damp shop environment. The hex socket drive gives a nice, secure fit without any cam-out issues. For the price of a 400-pack, these are a solid buy for precision fasteners.

Used a handful to replace rusted fasteners on a saltwater fishing jig — the 316 stainless held up perfectly after a week submerged. The 25mm length gave just enough bite into the aluminum frame without bottoming out. Exactly what I needed for precision assembly work.

The hex socket drive bit right into my 3D printer's hotend mount without any cam-out, and the 316 stainless gives me confidence it won't corrode near the heated bed. For the price per bag, these little screws are a steal for precision work.
