I needed some long lag bolts for a tree fort. Fasteners Plus had the product and shipped quickly. Shipping was pricey, but the package was an unusual size and heavy. I could not find what I needed on Amazon. The one drawback was that I could not locate the appropriate nuts and washers on their website. I suppose I could have called. I would suggest to their web manager to link the appropriate washers and nuts when ordering bolts. I did find what I needed at our local Menards. Menards does not carry the desired bolts in the required length.
My husband are Do it ourselves kind of people and we built a pergola, but needed longer
bolts that cannot be found in most Hardware stores. Searched around and found Fasteners Plus and received our order in 3 days. Thank you so much.
Recently recieved the exact size bolt I really needed for my e-bike, at a decent price, good service, and with speedy shipping. Therefore, I recommend these products and rate this company with a full 5 stars 🌟
