M20-2.5 X 230mm 六角頭螺絲 | 316 不鏽鋼 | 部分螺紋 (5 / 包)

The threads were clean and started easily with just a hand wrench, which saved time aligning the frame. Used a few to bolt down a small press, and the 316 stainless feels solid even in damp conditions.

Installed these on a heavy plate compactor, and the 316 stainless is holding up perfectly despite constant vibration and moisture. The hex head gave my socket wrench a solid grip, and the partial threads let me fine-tune the seating depth.

The partial threading made it easy to get a solid bite on my equipment frame without having to fight the full length, and the hex head seated perfectly with a standard socket wrench. For the price, the 316 stainless build feels robust enough for heavy-duty outdoor use.
