M8-1 x 20mm 六角頭螺絲 | 10.9級鋼材 無鍍層 | 全牙 (500顆/包)

Used these to secure some heavy duty shelving brackets to a concrete wall. The threading was clean and they seated perfectly with a socket wrench, no stripping at all. Honestly, a solid pack of hardware for the price.

Put together a steel workbench frame with these and they drove in cleanly without stripping. The class 10.9 rating gives me confidence it'll hold up under heavy loads.

Used these to fasten a new motor mount on a workshop press, and the hex heads held torqued down perfectly without any stripping. The fully threaded shank made alignment a breeze during assembly.
