7/16-14 X 5" 車用螺栓 | 全螺紋 | A307 A級普通鋼 (175 / 包)

The fully threaded length on these is a real time-saver, letting me cut them down to exact sizes for a pergola build without wasting a single bolt. The smooth rounded head sits flush and looks clean, and all 175 arrived without a single bent thread.

The square neck under the head grabbed nicely into the wood without spinning, which made installing all 175 of them a smooth job. For a plain steel bolt at this price point, the threading was surprisingly consistent across the whole box.

These bolts fit perfectly into my deck frame and the square neck grabbed the wood tight so nothing spun while I tightened the nut. For 175 pieces in a pack, this is a solid deal for heavy-duty projects. The plain steel finish is exactly what I expected for indoor use.
