3/8-16 X 6" 六角頭螺絲 | 8級鋼 鍍鋅 | 部分螺紋 (200 / 包)

After fighting with cheaper bolts that kept snapping, these hex heads tightened down beautifully with a socket wrench. The partial threading gave just the right grip for my jig assembly.

These Grade 8 bolts were exactly what I needed to rebuild a hydraulic pump mount on a log splitter. The zinc coating looks good and the threads are clean and sharp, they chased right in without any binding. Solid hardware for the money.

Used these on a skid-steer attachment where standard bolts kept snapping; the Grade 8 rating held up perfectly under heavy load. The zinc plating also stayed intact after a few days in light rain.
