براغي رأس سداسي 5/8-18 × 4-1/2 بوصة | فولاذ درجة 5 زنك أصفر | خيط جزئي (25/عبوة)

These bolts threaded in smooth and easy for a tough repair on my tractor’s PTO shaft. The hex head grabbed the socket perfectly without any stripping.

The yellow zinc coating on these is really clean and even, which made them easy to grip with a socket without any slipping. They threaded into my equipment stand smoothly, and the partial thread gave me just the right amount of bite for a secure hold.

The partial threading on these 5/8-18 bolts made alignment a breeze when I bolted down my lathe stand, and the yellow zinc finish still looks clean after a week of shop dust. Grade 5 steel feels plenty tough for the torque I put on them with a socket.
