براغي ذات رأس أسطواني #10-24 × 3/8 بوصة | محرك سداسي | فولاد سبائكي (1000 / عبوة)

The hex socket drive bites perfectly every time, so these went into my tooling jigs without a single stripped head or wasted piece. Alloy steel feels plenty sturdy for the precision assemblies I'm running.

I needed a full thousand for a batch of jigs and these came perfectly burr-free, so the hex socket accepted the wrench without any binding. The alloy steel feels noticeably stiffer than the cheap zinc-plated ones I used before.

The hex socket drive grips the Allen key perfectly without any stripping, even when I’m torquing them down in tight spots. For a thousand pieces at this price, the alloy steel feel is solid and consistent. I’ve already burned through half a box on my jigs and haven’t hit a single bad thread.
