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.
