براغي آلية 1/4-20 X 3-1/2" | رأس دائري مشقوق | فولاذ مطلي بالزنك (300 / عبوة)

Zinc plating is holding up nicely so far—no rust after a week of outdoor use, and the round heads seat flush without stripping. These 3-1/2" lengths are perfect for my metal panel enclosures, and 300 in one box means I won’t be reordering any time soon.

I was pleasantly surprised by how smooth the threads are on these 1/4-20 bolts—they started by hand without any binding. Used them to mount some heavy steel brackets and the zinc plating held up well against my wrench.

Exactly the right length for bolting together steel enclosure frames — the zinc coating looks evenly applied and the slotted heads seat nicely with a standard screwdriver. Used about half the box on a weekend project and not a single stripped thread or dud in the bunch.
