مسامير عربة 1/4-20 × 1-1/4 بوصة | ملولبة بالكامل | A307 درجة A فولاذ مطلي بالزنك (500 / عبوة)

The square neck on these bolts grabbed perfectly into the wood on my shed frame, no slipping while tightening. They’ve held up well through a few rainstorms without any rust yet.

The square neck under the head really bites into the wood—I didn't have to hold a single bolt in place while tightening. All 500 threads were clean and the zinc coating looks even, no stripped ones in the whole box.

Used a full box of these to build a heavy-duty workbench, and the fully threaded shaft made it easy to get a tight fit with a lock washer. The zinc coating on these seems thick enough to resist the humidity in my garage so far.
