M12-1.5 X 45mm 六角頭螺絲 | 8.8級鋼 原色 | 全牙 (100顆/包)

The fully threaded length on these saved me a trip to the hardware store when I needed extra grip on a jig build. Class 8.8 steel feels solid for the price, and the hex heads drove cleanly with my socket wrench without stripping.

Used these to secure a heavy motor mount on a press, the 8.8 grade steel held torque without stripping. The hex heads fit a standard socket perfectly, no slippage. Good, solid fasteners for the price.

The threads are perfectly clean and the hex heads seat snugly in my socket with zero wobble, which made tightening them on the conveyor frame a breeze. This full box of 100 will last me ages for shop repairs, and the class 8.8 rating gives me confidence they won't strip under load.
