Joseph R. ★★★★★

The threads on these hex head cap screws are really clean, threaded smoothly into the tapped holes on my press without any binding. The zinc coating looks evenly applied and should hold up fine in a garage environment. Definitely solid for heavy-duty equipment assembly.

Robert C. ★★★★★

The zinc plating on these M30 screws is noticeably even, helping them slide smoothly into a tapped hole without binding. For a 120mm partially threaded fastener, the bite on the threads feels just right for heavy equipment assembly. Will be buying more for the next job.

Lucy U. ★★★★☆

Used these for mounting a heavy press plate—the 8.8 steel handled the torque well with no thread stripping. My only nitpick is the plating’s a bit thin on a couple of heads, leaving them looking dull. Still, they fit the socket drive perfectly and got the job done.
