Customer Reviews (5.0 / 5 · 5 reviews)

Isabella ★★★★★

Waited two weeks for a 170mm length in 18/8 stainless, but the fully threaded body threaded clean into a steel bracket without binding. The hex head grabbed the wrench firmly, no stripping—exactly what I needed for a heavy equipment mount.

Hannah ★★★★★

The hex heads fit perfectly with my socket wrench, and the 18/8 stainless steel feels solid. These 170mm screws were just the right length for my machinery assembly.

John ★★★★★

The fully threaded length on these is a lifesaver for lining up misaligned flanges, and the 18/8 stainless finish feels solid and corrosion-resistant. Tightened them with a socket drive without any stripping, which is more than I can say for cheaper bolts.
