مسامير رأس سداسي 5/16-24 × 3-3/4 بوصة | فولاذ درجة 5 زنك أصفر | ملولبة جزئيًا (50/عبوة)

The partially threaded shaft makes these sit flush without bottoming out, which saved me a headache on a bracket assembly. Yellow zinc coating looks consistent across all fifty, and the hex heads grabbed cleanly with a socket. These are exactly what I needed for the job.

I needed something sturdy for a heavy machinery mount—these partially threaded screws grabbed tight and held with no wobble.

Used these to bolt down a workbench tabletop and the partially threaded shank gave just the right amount of grip without stripping. The yellow zinc coating looks clean and seems like it'll hold up well in my garage.
