براغي ذات رأس سداسي 5/16-24 × 1-3/4" | درجة 5 فولاد مع زنك أصفر | ملولبة جزئيًا (100 / عبوة)

Arrived well-packed and the hex heads drive cleanly with a socket. The yellow zinc finish looks just as described, no rust spots. Solid pack for shop use.

The partial threading on these made them ideal for my equipment jig, where I needed a smooth shank section for alignment. The yellow zinc finish looks consistent across all 100 pieces and they drive cleanly with a standard socket.

These hex bolts tightened down perfectly on my milling machine’s hold-down clamps, and the yellow zinc coating looks clean and even across all 100 pieces. The grade 5 steel feels sturdy, and the partial thread made aligning the through-hole a lot easier than dealing with a fully threaded shank.
