براغي رأس سداسي M4-0.7 × 20 مم | فئة 8.8 فولاذ عادي | كامل الخيط (8000/عبوة)

Used these to secure some brackets on a production line, and the 8.8 steel held torque perfectly without stripping. For an 8000-count box, the price per screw is hard to beat. Will definitely order again for future projects.

The hex heads drive perfectly with a socket, and these Class 8.8 bolts held my machine frame together without any stripping. For 8,000 fasteners at this price, they're exactly what I needed for production runs.

These are properly threaded all the way, and the 20mm length works well for the bracket assembly I was working on. No stripped heads or burrs in the whole box.
