براغي رأس سداسي 1/4-20 × 3" | فولاذ درجة 5 أصفر زنك | ملولبة جزئيًا (100/عبوة)

Bought these to secure a jig on my drill press table, and the partially threaded design gave me just the right grip without bottoming out. The yellow zinc coating looks exactly like the picture and hasn't shown any rust after a few weeks in the shop.

These held perfectly when mounting a heavy-duty shelf bracket to a steel beam; the partial threading made starting them much easier. The yellow zinc coating looks good and seems like it will resist rust well.

Installed these in a jig I built for a metal brake, and the partial threading grabbed just the right amount without bottoming out. The yellow zinc coating looks clean and seems tough enough to resist the occasional splash of cutting oil.
