براغي رأس سداسي M18-2.5 × 55 مم | فئة 8.8 فولاذ مطلي بالزنك | كامل الخيط (20/عبوة)

The zinc plating on these hex bolts looks clean and even, and they threaded smoothly into my steel frame without any binding. They felt solid under the wrench, just what I needed for a heavy assembly job.

Used these for mounting some heavy steel brackets and the Class 8.8 zinc plating held up perfectly against the wrench without any stripping. The fully threaded shaft gave a really solid grip, and all twenty screws had consistent, clean threads.

The threading is perfectly clean, so these screws drove in without any binding. I used them to secure a steel bracket to a frame, and the zinc plating looks like it'll hold up fine.
