M10-1.5 X 20mm براغي ذات رأس أسطواني بمقبس سداسي | كامل الخيط | فئة 12.9 فولاذ سبائكي مطلي بالزنك (600 / عبوة)

Was a bit skeptical about buying bulk hardware online, but these screws are exactly the right spec for my CNC fixture builds. The hex drive is cleanly broached and the threads cut smooth without binding.

Used a handful to repair a jig at work; the hex socket drive made installation quick with no stripping issues. The zinc coating feels durable, and the 12.9 hardness handled the torque perfectly.

Packed the full 600-count box exactly as listed, and every single screw has clean threads and a uniform hex socket. I used them to rebuild a jig fixture at work and they torqued down perfectly without any stripping.
