براغي رأس أسطوانية مجوفة M2 × 3 مم | محرك سداسي مجوف | فولاذ مقاوم للصدأ 316 (400 / عبوة)

The hex drive really grabs the driver bit without stripping, which was my main frustration with cheaper stainless screws. I've used a dozen already in a jig project and they thread in smoothly without binding. Exactly what I needed for precision assemblies.

Finally found a pack of M2x3mm screws that doesn't strip on the first torque—the hex socket bites cleanly every time. Used a handful to rebuild a small jig and they held up without any corrosion worries. Four hundred pieces means I won't be ordering again for a while, which is exactly what I wanted.

Repairing a saltwater aquarium’s pump bracket, and the 316 stainless means no rust worries at all. The hex socket drive made installing them into tight spots much easier than a flathead would have.
