M12 X 45mm براغي ذات رأس أسطواني | محرك سداسي داخلي | سبائك فولاذية (100 قطعة/عبوة)

I needed a full pack of jigs secured this week and the alloy steel finish on these M12s feels properly tough, no burrs on the threads either. The hex socket seated perfectly with my driver, so they're going straight into the fixture builds. Exactly what I hoped for when ordering a hundred at this pr

The socket drive on these M12 screws fit my hex key perfectly with zero stripping or wobble, which made mounting jigs a breeze. Alloy steel feels dense and the 45mm length was exactly right for my precision assemblies. Third pack I've bought, same consistent quality every time.

Had to swap out the bolts on a jig setup, and these cap screws threaded in cleanly without any binding. The alloy steel feels sturdy enough for shop use, though I wish the kit included a few extras for the price.
