براغي رأس سداسي 3/8-16 × 5-1/2 بوصة | صناعة أمريكية | سبيكة فولاذ درجة L9 زنك أصفر | ملولبة جزئياً (300 / عبوة)

The yellow zinc coating is holding up great on these, no rust after a few weeks in a damp shop. The hex heads grab a wrench cleanly every time, and with 300 in the box I’ve got plenty for the rest of the job.

The partially threaded design makes these perfect for my jig builds, and the hex heads hold up well under a socket. Pack of 300 gives me plenty for the shop without breaking the bank.

The plating on these is a nice, even yellow zinc that feels like it'll hold up on the shop floor. Threads cut clean on both the machine side and the nut, and that partial thread gave me the grip I needed for a heavy bracket.
