M12-1.5 x 90mm 육각 머리 나사 | 클래스 8.8 강재 무도금 | 부분 나사산 (50개/팩)

The threads cut cleanly and the hex heads seated perfectly with a standard 19mm socket, no stripped corners or burrs. For the price per piece, these are solid Class 8.8 bolts that held up fine under moderate torque.

Used these to secure a heavy motor mount on a press, and the 90mm length gave just enough thread engagement without bottoming out. The partial threading made alignment easier than with fully threaded bolts. No stripped heads or deformation during torquing.

The hex head fits my socket perfectly, making installation on machinery frames quick and easy. These 90mm bolts hold up well under tension without stripping.
