Customer Reviews (4.8 / 5 · 5 reviews)

Ruby X. ★★★★★

These 18-8 stainless lag bolts are holding up perfectly on my outdoor machinery project, no rust after two weeks of rain. The hex head drives in cleanly without stripping.

Amelia S. ★★★★★

The hex head grabbed my socket wrench perfectly without slipping, and the 18-8 stainless steel feels solid for my heavy machinery project. These lag bolts drove into the steel frame cleanly with no stripping.

Michael ★★★★★

Used these to tie a pergola frame into the deck structure, and all 50 came out of the box perfectly clean with no burrs on the threads. The 18-8 stainless is a real step up from the coated zinc ones I’ve fought with before—they drove in straight without snapping.
