Customer Reviews (4.6 / 5 · 5 reviews)

Abigail ★★★★★

I needed these for a heavy-duty machine frame repair, and the partial threading made alignment much easier than with fully threaded bolts. The 8.8 steel feels solid, no flex when torquing down.

Zoe ★★★★★

The hex heads fit my socket perfectly without any wobble, and the 8.8 steel feels sturdy enough for heavy machinery assembly. These 100mm partially threaded screws worked great for securing a motor mount.

Richard R. ★★★★★

I needed heavy-duty fasteners for a machine base and these M30-3.5's were plenty strong—the class 8.8 steel feels solid and the partial threading gave me just the right grip depth.
