براغي رأس سداسية 5/8-18 × 3-1/4 بوصة | فولاذ درجة 5 مطلي بالزنك الأصفر | ملولبة جزئيًا (25/عبوة)

Installed these on a heavy press frame where I needed partial threads for the last inch — they seated perfectly with a socket. The yellow zinc coating is a nice touch for light corrosion resistance.

The yellow zinc coating on these Grade 5 bolts looks uniform and hasn't scratched during my installs, which is more than I can say for cheaper hardware. The partial threading gave me just the grip I needed on a jig without the threads chewing into the wood.

These bolts have a nice, clean yellow zinc finish and the partial threading made it easy to secure a heavy bracket without binding. Used them to mount a motor mount and they torqued down perfectly with a socket. Exactly what I needed for the job.
