9/16-12 × 4" براغي رأس سداسي | فولاذ درجة 5 مطلي بالزنك الأصفر | خيط جزئي (25/عبوة)

Used these to rebuild a pallet rack and the hex head sat flush without stripping. The yellow zinc finish held up fine against a little rain during install. Solid grip with a 9/16 socket, exactly what I needed.

The partial threading made seating these in a tight bracket way easier than I expected. Yellow zinc finish looks uniform across all 25, and the hex heads grabbed cleanly with a socket. Solid grip for the price.

I used these to fasten some heavy equipment brackets, and the grade 5 steel handled the torque without stripping. The partially threaded design gave me plenty of grip for the load.
