براغي رأس سداسي 1/2-13 × 9 بوصة | درجة 5 فولاذ أصفر زنك | ملولبة جزئيًا (6/عبوة)

The threading was clean and started easily into a tapped hole on my press jig, which saved me from fighting with cross-threading. These bolts feel solid for heavy-duty assembly work.

Needed heavy-duty bolts for a press rebuild; these Grade 5 cap screws torqued down perfectly with no stripping. The yellow zinc coating gives a nice corrosion barrier, and the partial threading made alignment much easier.

Perfect thread engagement on my lathe's tool post — the grade 5 steel and yellow zinc finish are holding up great after a week of heavy use. The partial threading made alignment a breeze, and the hex head grabbed my socket without any stripping.
