What Our Customers Say

These guys always have what I’m looking for in stock. I got tired of going to Home Depot to in search of the fasteners I needed for a project only to find out that either they didn’t stock that size, they were out of them or they only had packages of one or two of that particular fastener. Not to mention spend 15 minutes sorting through various packages put back in the wrong place. I’m always building or repairing things and some of the fasteners I need are a weird size. Marsh Fasteners always has them in stock, their staff is polite, and their prices are fair.
