M6-1 x 16mm 六角頭螺絲 | 316 不鏽鋼 | 全螺紋 (300 個/包)

Had to replace some rusty screws on outdoor equipment, and these 316 stainless steel ones fit perfectly with a hex driver. The fully threaded body gripped tight and should hold up way better than the old hardware.

Installed these on a saltwater dock railing and the fully threaded design made tightening a breeze. The hex head bit into my socket perfectly without slipping. Exactly the corrosion resistance I needed.

The 316 stainless finish is exactly what I needed for outdoor equipment—no rust worries after a month of rain. The fully threaded design gripped perfectly in my bracket, and the hex head gave me solid torque without stripping. A full pack of 300 means I won't be reordering for a while.
