مسامير عربة مقاس 1/4-20 × 3-1/4 بوصة | ملولبة بالكامل | فولاد ستانلس ستيل 316 (50 / عبوة)

The square neck grabbed into the wood immediately on my first test piece—no spinning or wrench needed to hold it steady. The 316 stainless finish looks clean and the threads ran smooth all the way down on all 50 bolts.

Used these to rebuild my dock railing and the fully threaded shaft made them easy to secure with a washer and nut. The 316 stainless seems like it’ll hold up well to the saltwater exposure.

The square neck on these carriage bolts grabbed into the wood perfectly on my deck repair, no spinning at all. Fully threaded makes them versatile for different thicknesses, and the 316 stainless should hold up well against the salt air here.
