براغي غطاء مقبس M3-0.5 × 25 مم | رأس مسطح سداسي المقبس | ملولبة بالكامل | فولاذ مقاوم للصدأ 316 (600/عبوة)

Put a set of these in for a marine railing repair and the 316 stainless is holding up perfectly to salt spray. The hex drive seats nicely without stripping, and the fully threaded length gave me good grip in thin aluminum.

Finally, a stainless cap screw that doesn’t strip the hex drive on the first use—these cut cleanly into aluminum jig plate without galling. The fully threaded length saved me from having to stack washers on a tight bracket.

I’ve been through a lot of cheap M3 screws that strip, but these 25mm ones hold up great—the hex socket drive is really solid, and the 316 stainless just feels tougher than the usual 304. I’m using them for jigs and they’ve been perfect so far.
