براغي ذات رأس مقبس M3-0.5 X 25mm | محرك مقبس سداسي | ملولبة جزئياً | فولاذ مقاوم للصدأ 316 (600 / عبوة)

The hex sockets are cleanly cut, so my Allen wrench seats perfectly every single time without any wobble or stripping. I've used about a third of the 600 for jig frames and haven't found a single burr or inconsistent thread yet.

Running a batch of these through a small jig project and the 316 stainless finish feels much more corrosion-resistant than the cheap zinc-plated ones I used before. The hex socket drive made it easy to get a consistent torque without stripping. Exactly what I needed for precision assemblies.

Installed these on a few jigs and the 316 stainless steel is holding up perfectly in a slightly damp shop environment. The hex socket drive grips firmly without any cam-out.
