7/16-20 × 4" براغي ذات رأس سداسي | فولاذ درجة 5 أصفر زنك | ملولبة جزئيًا (25 / عبوة)

The partial threading on these bolts made it easy to get the guard mounted without fighting the threads the whole way. The hex head seated perfectly with my socket, and the yellow zinc coating looks clean and professional. A solid upgrade from the generic hardware I had before.

I needed long bolts for mounting a guard to a heavy machine frame, and these 7/16-20 cap screws with the hex head worked perfectly with my socket set. The yellow zinc coating on the grade 5 steel looks solid and should resist rust in my shop.

The partial threading on these made them perfect for clamping down a thick fixture plate without bottoming out. Grade 5 finish feels solid and the yellow zinc coating looks clean.
