1-1/4-7 x 6" 重型六角頭螺絲 | 18/8 不鏽鋼 | 部分螺紋 (2 顆/包)

Bought these to bolt down a piece of shop equipment and the 18/8 stainless has held up with zero rusting so far. The partial threading gave me clean thread engagement without the shank bottoming out early. Heads took a 2" socket without rounding.

The 18/8 stainless is the real deal — I left one bolted to a dock bracket through a full winter of salt spray and it didn't pit at all. The 6" length gives plenty of shank for clamping thick steel plates, and only the last couple inches are threaded, which is exactly what I needed.

Bought these to bolt down a tractor implement and the 1-1/4-7 size threaded in without any slop. The stainless finish hasn't shown a spot of rust after sitting outside in the rain. Six inches of shank gave me plenty of grip through the thick bracket.
