Jacob ★★★★★

I needed a solid 4-inch lag bolt for a heavy machinery mount, and these stainless steel ones fit perfectly. The 18-8 material feels sturdy and hasn't shown any rust after a month in a damp garage.

Timothy X. ★★★★★

The hex head grips my socket wrench perfectly with no stripping, and the 18-8 stainless finish looks clean and solid. I’ve got 50 of them, so I can finish my deck framing and still have plenty left for future projects.

Claire C. ★★★★★

I needed some corrosion-resistant fasteners for a dock repair project, and the hex head on these gave my socket wrench a solid grip without any stripping. The 4-inch length drove deep into the pressure-treated lumber, and the 18-8 stainless finish should hold up against the saltwater splash.
