1/4-20 × 3" براغي آلية | رأس مسطح 82° مع محرك مشقوق | فولاذ مطلي بالزنك (400/عبوة)

The zinc plating on these screws is holding up well so far with no rust after a few weeks in a slightly damp garage. I used a whole box mounting metal brackets and every single one drove in cleanly with no stripped heads.

The 82-degree flat heads sit perfectly flush in the metal panels I’m joining, and the zinc plating has held up well without any corrosion. These are exactly the length I needed for a heavy-duty enclosure.

These replaced a box of mixed bolts I've been hoarding for years, and the uniformity is a huge relief. The 82° flat head sits perfectly flush in my counterbores, and the zinc plating looks clean without any tool marks. Honestly, having 400 of the exact same size in one box is a beautiful thing.
