M10-1.5 X 35mm 六角頭螺絲 | 等級 10.9 鋼 原色 | 部分螺紋 (600 個/包)

I needed a bulk supply of fasteners for some heavy equipment frames, and the hex heads on these 10.9s bit into the socket perfectly. The 35mm length gave just enough thread to clamp down securely, and not a single one stripped during assembly.

These bolts threaded smoothly into the mounting brackets I'm using on a steel frame project. The partial threads made it easy to start by hand before using a socket.

Packed 600 of these in a box for a big assembly run and the class 10.9 steel feels properly tough, not like the flimsy zinc-plated ones I've used before. The partial threading grabbed nicely in the blind holes, no stripped heads even with an impact wrench. Solid buy for the price.
