Customer Reviews (4.8 / 5 · 5 reviews)

Matthew I. ★★★★★

Installing these on a heavy-duty press, the full threading made all the difference for a secure grip. The hex head took a socket wrench perfectly without any stripping. Zero complaints.

Olivia G. ★★★★★

These 10.9 grade hex bolts held up perfectly when I torqued them down on a heavy press fixture—no stripping at all on the fully threaded shank. The hex head gave my socket wrench good bite without slipping. Exactly what I needed for industrial assembly work.

George ★★★★★

The 120mm length was perfect for getting through the thick frame assembly, and the class 10.9 steel feels really solid under the socket wrench. These held tight without any stripping, even driving them into hard metal.
