M18-2.5 X 40mm 六角頭螺絲 | 10.9級鋼原色 | 全螺紋 (150個/包)

Needed exactly M18x2.5x40mm for a jig rebuild, and these class 10.9 bolts seated perfectly with no thread binding. The hex head gave my socket a solid bite. Pack of 150 will last me years.

Finally, a batch of hardware where every single screw has clean, burr-free threads. Used these to bolt down a heavy conveyor guard and the hex heads seated perfectly with no slipping.

The threading is clean and uniform across all 150 pieces, and the hex heads seated perfectly with a socket wrench on our conveyor frame. These 10.9-grade bolts have held up solidly for two weeks of heavy vibration with zero backing out.
