5/16" x 5" Conquest Hex Head Lag Bolt for Wood - 18-8 Stainless Steel

This 5/16" x 5" Conquest Hex Head Lag Bolt for Wood - 18-8 Stainless Steel delivers long-reach holding power for thicker wood assemblies. The coarse threading grabs deep into framing lumber, and the 18-8 stainless steel build resists rust, even in demanding outdoor environments. Its hex head ensures consistent torque application, making it an ideal solution for deck posts, beams, and other long-span fastenings.

Stainless Lag Screw Review

I needed an uncommon size, and Fasteners Plus had just what I needed. It was quickly delivered, and the order was accurate, and the quality was excellent.

Small order

I was very satisfied with the lag screws I purchased. My only issue with Fastners + is with the standard shipping cost. Unless I order a large quantity, the shipping cost charged is exorbinate.
