M20-2.5 X 190mm براغي ذات رأس سداسي | فولاذ فئة 8.8 غير معالج | ملولبة جزئيًا (10 / عبوة)

Finally got these for a heavy equipment repair job, and the length and partial threading give me plenty of thread engagement without bottoming out. Used a socket drive on them, and the hex head grips perfectly without any slipping.

These threads cut clean on the first pass and the hex head grabs a socket without any wobble. The partial thread is just right for clamping thick flanges, and the 190mm length gave me enough bite for my press setup.

Class 8.8 steel feels sturdy enough for heavy machinery assembly, and the hex head caught the socket nicely. Only minor quibble is the thread length is a bit shorter than I expected for the size.
