M16-2 X 40mm 六角頭螺絲 | 316不鏽鋼 | 全螺紋 (25顆/包)

Had to replace some old bolts on a heavy gate mechanism and these M16 hex heads threaded in without any binding. The 316 stainless steel gives me peace of mind that they won't rust out by the coast.

Matched the original rail bolts perfectly on an old assembly line fixture that had been rattling for years. The 316 stainless takes the grinder marks without rusting, and the fully threaded length gives plenty of grip. Solid fix for the price.

Used these to rebuild a marine railing on my boat; the 316 stainless is already proving way more corrosion-resistant than the old hardware. The fully threaded design made aligning the bolts a breeze with just a socket.
