براغي رأس سداسي M12-1.25 × 110 مم | فئة 8.8 فولاذ مطلي بالزنك | ملولبة جزئيًا (25 / عبوة)

I needed these for a heavy duty equipment repair, and the Class 8.8 steel feels solid under the wrench. The partial threading made installation much easier than expected.

Replacing the ones on my lathe carriage was painless because the partial threads bit cleanly and the zinc coating hasn't flaked after a week of oil and chips. The 8.8 hardness feels solid when torqued, and all 25 heads were true for a socket, no rounded corners in the batch.

Put a set on a small assembly press I was repairing—the partial threads let me grip exactly as needed. Zinc plating looks consistent, and all 25 hex heads fit the socket cleanly without any stripping.
