براغي رأس سداسي 1/4-20 × 2-1/2 بوصة | صناعة أمريكية | فولاذ سبائكي درجة L9 مطلي بالزنك الأصفر | ملولبة جزئيًا (100 / عبوة)

The yellow zinc finish on these L9s is properly done—even after wrenching a few down snug, the coating didn't flake or scratch off. Threads ran clean into my steel brackets without any binding, and the partial thread made alignment a breeze for the 2-1/2" length I needed.

Used a handful of these to bolt a heavy-duty bracket onto my press, and the yellow zinc coating has held up perfectly without any rust so far. The partially threaded design made alignment much easier than with fully threaded bolts.

The threads are cut perfectly true on every one I've used so far, and that yellow zinc finish has held up nicely against the grease and grime in my shop. For a hundred pack of this grade, it's a solid deal if you need a serious stock of bolts.
