براغي رأس سداسي 1-3/4-5 × 9 بوصة | فولاذ سبائكي درجة BD عادي | ملولب جزئيًا (1/عبوة)

Used these to replace some worn-out fasteners on an old press machine, and the hex head made wrench access a lot easier than I expected. The partial threading grabbed perfectly without bottoming out, and they feel solidly built.

Grading BD alloy steel is no joke—these things torqued down smoothly without a hint of stripping, even at full 9" length. Partially threaded design grabbed exactly where I needed it for the heavy equipment brace. Already ordered more.

These bolts handled the heavy torque I needed for mounting a press without stripping, and the partial threading made alignment much easier. The alloy steel feels solid and reliable.
