مسامير رأس ثقيلة سداسية 1-1/4-7 × 4-1/2" | ستانلس ستيل 18/8 | ملولبة جزئيًا (2 / عبوة)

I needed these for a dock repair and the 18/8 stainless held up great in saltwater spray. The 4-1/2" length and partial threading gave me plenty of grip through the doubled-up lumber. Heads took a 1-1/4" socket without rounding.

Bought these to bolt down a trailer hitch and the 18/8 stainless hasn't shown a speck of rust after a wet winter. The 1-1/4-7 thread grabbed clean and the 4-1/2 length left just enough shank for the plate and nut.

Bought these for a tractor implement rebuild and the 18/8 stainless held up fine against the weather so far. Only gripe is the partial thread ends sooner than I expected, so I had to swap to a longer size on one joint. Solid hardware for the price.
