M5-0.8 x 35mm 六角頭螺絲 | 8.8級鋼 無處理 | 全螺紋 (3500顆/包)

Finally found a pack of M5-0.8 x 35mm hex heads that are all consistently threaded and clean; the hex drive fits my socket perfectly without any wobble. These 8.8 steel screws feel solid enough for repetitive assembly work, and getting 3500 in one bag saves me multiple trips.

Pulled out enough for a full production run and the thread quality is consistent throughout every single piece. The hex heads grab a socket cleanly without any stripping, which matters when you're driving 3,500 of them. Class 8.8 steel gives me confidence these won't shear under load.

I’ve been using these M5 hex head screws for mounting frames on some steel beams, and the Class 8.8 steel holds tight even under heavy vibration. The fully threaded shank made it simple to get a consistent bite in each hole.
