M48-5 X 220mm 外六角頭螺絲 | 10.9級鋼 無處理 | 半牙 (5/包)

Used these to mount a heavy jig frame, and the class 10.9 steel took the torque without a hint of flex. The partial threads made alignment easier than I expected for such a large bolt.

The hex heads on these M48 bolts are machined perfectly, and my socket grabbed them without any slip during assembly. They’ve got a solid, heavy feel that you’d expect from Class 10.9 steel, and the partial threading made alignment a breeze. Exactly what I needed for securing heavy machinery.

The extra length on these M48 cap screws let me fasten a heavy support bracket that the shorter bolts I had couldn't reach. The hex head fit my socket perfectly without slipping.
