5/16" × 1-1/4" براغي رأس سداسية | ستانلس ستيل 316 (1000 / عبوة)

I was tired of replacing rusty lag screws on my outdoor deck, so I grabbed these 316 stainless ones. The hex head and 5/16" thickness made them a breeze to drive into the treated lumber without stripping.

The 316 stainless steel is the real deal here, the heads didn't strip once even when I torqued them hard into oak. A full box of 1000 means I won't be running out for any future deck or timber projects, which honestly is the best part.

Installed a dozen of these in a treated wood retaining wall last weekend, and the 316 stainless held up perfectly through a heavy rain without any surface rust. The hex heads grabbed onto my socket wrench securely for a tight fit. Exactly what I needed for outdoor timber connections.
