Customer Reviews (5.0 / 5 · 5 reviews)

Daniel ★★★★★

Had to torque these down for a press frame repair, and the hex head held up perfectly with a socket wrench—definitely beefy enough for industrial use. The class 8.8 steel feels solid.

Carter ★★★★★

Installed these on a heavy assembly jig and the M48-5 threads engaged smoothly with no binding. The 400mm length was exactly what I needed for a through-bolt application.

Julian ★★★★★

The hex heads on these bolts fit my socket perfectly without any rounding, and the 400mm length gives just enough thread engagement for heavy flange connections. The plain Class 8.8 finish holds up well under moderate torque.
