AN4-30A | 軍規螺栓 (10 / 包)

These bolts held up perfectly when I used them to replace the fasteners on my shop press. The threads were clean and engaged smoothly without any binding, and the whole set came well-protected in the package.

Using these for a heavy equipment frame rebuild, the threads caught cleanly on the first pass every time. The finish is consistent across all ten bolts, no burrs or defects to fight with.

Pulled these out for a machinery assembly job and the threading was clean and consistent on every single bolt. Fit snugly without any wobble, which I really appreciated.
