براغي ذات رأس أسطواني M5-0.8 × 8 مم | رأس مسطح بمحرك سداسي مجوف | ملولبة بالكامل | فولاذ مقاوم للصدأ 316 (600/عبوة)

I was a little worried about the quality when I saw the price per piece, but these are properly made 316 stainless—no burrs on the threads and the hex drive fits snugly. I've used about a hundred so far on a jig build and not a single stripped socket. For 600 pieces, I'm set for years.

The hex socket drive on these is machined cleanly, so my Allen key seated perfectly without any wobble. I used a full box on a stainless steel jig and every single one of the 600 threaded in smoothly.

Had to replace some cheap screws on a saltwater-exposed jig and these 316 stainless ones are holding up perfectly, no rust after weeks of use. The hex socket drives cleanly without stripping, which is a huge plus for precision assemblies. Exactly what I needed for the price per piece.
