This 3/4" x 3-1/2" Conquest Hex Head Lag Bolt for Wood - 18-8 Stainless Steel features a 4-1/2 TPI coarse thread engineered for maximum grip and deep penetration in structural wood applications. Made from high-quality 18-8 stainless steel, it provides strong resistance to corrosion and oxidation in harsh environments. The larger 3/4" diameter delivers superior load-bearing capacity compared to smaller lag bolts. Its hex head design supports high torque installation, making it ideal for demanding structural or outdoor jobs.

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.
