M36-4 x 240mm 六角頭螺絲 | 10.9級鋼 無處理 | 部分螺紋 (1入/包)

Put my 1-ton press back together after stripping the old bolts — these M36-4 x 240mm cap screws threaded in smooth and the hex head grabbed my socket wrench perfectly. No wobble, no fuss, just solid holding power. Exactly what heavy machinery needs.

The partially threaded design made installation much easier than I expected for such a large bolt, and the hex head gripped perfectly with my socket. These M36x240mm fasteners feel incredibly solid for heavy machinery work.

These bolts are hefty, the 10.9 steel gives me confidence they won't strip out under heavy load. I used one to secure a large press base, and the partial threading helped get it started in the hole. Exactly what I needed for industrial equipment assembly.
