M16-2 x 140mm 六角頭螺絲 | 316不鏽鋼 | 全螺紋 (10 / 包)

Finally, a cap screw that's actually fully threaded all the way—the 140mm length gives great grip without any shank. The hex head sits perfectly in my impact socket, and the 316 stainless feels solid.

The hex head gave my socket wrench a solid grip without any slippage. These 316 stainless screws feel dense and well-made for the price. I used a full pack on a boat repair and they threaded cleanly into the pre-tapped holes.

Put a set of these on a heavy clamping fixture and the 316 stainless is holding up perfectly in a damp shop environment. The fully threaded length made it easy to get the exact grip I needed.
