M30-3.5 X 60mm 六角頭螺絲 | 10.9級鋼原色 | 全螺紋 (35入/包)

The hex head on these M30 screws grips the socket perfectly, so there's no slipping when tightening down heavy equipment. They fully thread into the nut with smooth, consistent torque, and the Class 10.9 steel feels solid for industrial use.

I was a bit worried about the 60mm length until I realized these are fully threaded, so they adjusted perfectly for a spacer setup on a heavy press. The hex heads are machined cleanly, no wobble when I put a socket on them. Whole package of 35 feels solid for the price.

The hex heads on these bolts grabbed my socket perfectly without any slippage during installation. Fully threaded along the whole 60mm length gave me just the right grip for a heavy machinery repair.
