M8 x 16mm 六角機械螺絲 | 316 不鏽鋼 | 全螺紋 (100入/包)

Installed these on a metal gate that faces the ocean, and the 316 stainless is holding up perfectly against the salt air. The full threading along the entire 16mm length gave me a solid bite into the frame.

Used these to fasten some outdoor furniture, and the 316 stainless steel is holding up perfectly against the rain. The fully threaded shank made it easy to get a tight grip in the wood frame.

Finally, a stainless bolt that doesn't immediately rust in coastal weather; the 316 grade on these M8 x 16mm hex heads is exactly what I needed for a damp location. Fully threaded along the shank made it easy to get a solid bite in the aluminum channel without any wobble.
