براغي رأس سداسي 5/16-18 × 1-1/2 بوصة | فولاذ درجة 5 مع زنك أصفر | خيط جزئي (1000 / عبوة)

These fit perfectly in my tractor's mower deck spindles and the partial threads made installation a breeze. The hex heads grabbed nicely with a socket wrench without stripping.

The yellow zinc finish on these held up perfectly through a week of outdoor use without a hint of rust, and the partial threading really helped my alignment during assembly. For a thousand pieces at this price per unit, they're a solid value for any shop stock.

Finally found bolts that actually fit my heavy equipment without stripping the threads. The yellow zinc coating is holding up well against the weather, and having a full box of 1000 means I won't run out mid-project.
