براغي رأس سداسي M20-1.5 × 55 مم | فولاذ فئة 8.8 عادي | ملولبة بالكامل (25 / عبوة)

The hex heads on these grabbed my socket perfectly without any wobble. I used a dozen to mount a steel bracket, and the class 8.8 strength feels solid for the price. Exactly what I needed for heavy equipment assembly.

Threads are clean and consistent all the way down, and the hex head grabs a socket without any wobble. I've got a fixture that needed M20 hold-downs and these seated flush with just a few turns. Class 8.8 feels solid enough for the job so far.

Used these to bolt down a heavy press in the shop and they seated perfectly with a standard socket, no stripping. The 55mm length was just right for our application and the full threading gave plenty of grip.
