براغي رأس سداسية M4-0.7 × 45 مم | فولاذ درجة 8.8 عادي | ملولبة بالكامل (400 / عبوة)

Built a small jig for my drill press and these m4-0.7 screws threaded in perfectly without any binding. The hex head seated deep and held firm with a standard socket driver.

Pulled these out to fasten a motor mount that kept vibrating loose, and the fully threaded shaft really grabs tight across the full 45mm. The hex head seats cleanly with a standard socket, no stripping so far. Class 8.8 steel feels solid for the price of a full pack.

These are exactly the length I needed for mounting some equipment brackets, and the hex heads let me get them tight with a ratcheting wrench. The fully threaded grip holds firm even under vibration.
