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

Swapped these onto my trailer's leaf spring hangers and the 18/8 stainless hasn't shown a hint of rust after a wet winter. The partial threading gave me clean clamping right where I needed it. Beefy heads take a big socket without rounding.

These went into the anchor bolts on my dock lift and the threads cut clean with no galling at all. Stainless was the whole reason I bought them and they've held up through a wet winter so far.

Rebuilt the gate hinge on my shop door and these 1-1/8-7 bolts fit the old bracket holes perfectly. The 18/8 stainless has zero rust after a rainy month outside, and the coarse threads bit into the wood without stripping.
