Riley ★★★★★

The wrench fit the hex head perfectly and these fully threaded M27s grabbed cleanly the whole way in. Class 8.8 steel feels solid for the price, and the zinc coating looks uniform without any flaking. Used them on a press frame and they haven't budged.

Olivia G. ★★★★★

Zinc plating really holds up well in my slightly damp workshop—no rust after a week on the press. The fully threaded design let me get a solid grip in some tight brackets. Perfect size for heavy machinery assembly.

Thomas F. ★★★★★

Putting together a hydraulic press table, these bolts threaded in smoothly and the hex head grabbed perfectly with my socket. The zinc plating on the fully threaded shaft held up well when I torqued them down too.
