1/4-20 X 3" 六角機械螺絲 | 鋼鍍鋅 | 部分螺紋 (200 個/包)

Finally ordered a full box of these instead of running to the hardware store every other week. The zinc plating looks clean and even, and the partial threading gave me a solid grip when I bolted two steel plates together. Exactly what I needed for the price.

The unthreaded grip section on these bolts made aligning my steel brackets so much easier, no fighting threads halfway through the connection. The zinc plating looks uniform and hasn't shown a speck of rust after a few rainy days outdoors. For a 200-pack, the price is hard to beat.

The threads are clean and the zinc coating looks uniform across all 200 bolts, which made them easy to run a die over for a custom fitting. The partially threaded shank gave me that solid grip length I needed for a steel bracket assembly, and the hex heads seated perfectly with a standard wrench.
