Customer Reviews (4.8 / 5 · 5 reviews)

Penelope ★★★★★

Perfect fit on my press brake assembly; the 50mm length grabbed just right and the zinc plating looks like it’ll resist rust well. These class 8.8 screws feel solid in the hand.

Joseph ★★★★★

The heads are machined cleanly so an M30 socket slips on without any wobble, and the zinc coating looks uniform across all five pieces. I used them to bolt down a heavy motor mount and the fully threaded shank grabbed tight the whole way through.

Lucy C. ★★★★★

Threads are clean and the zinc plating looks uniform across all five, so they should hold up fine in a damp shop. The class 8.8 rating gives me confidence torquing them down on the press frame without worrying about stripping.
