Metric Washers
Metric washers are essential components that work with screws, bolts, and nuts to ensure secure fastening and prevent loosening. We offer three primary types of metric washers: flat washers, lock washers, and spring washers. Each type plays a unique role in securing assemblies, distributing pressure, and absorbing vibrations.
Flat washers provide a larger surface area to distribute the load, while lock washers help prevent loosening due to vibrations. Spring washers provide tension to keep the assembly secure. These washers are available in various sizes and thicknesses, ensuring a proper fit for your application. For more information on sizes and types, visit our Metric Washers page.
Metric Nuts
Metric nuts are used in conjunction with bolts, screws, and threaded rods to create secure, vibration-resistant assemblies. We offer several types of metric nuts, including hex nuts, lock nuts, and cap nuts. These nuts are available in various thread sizes, pitches, and materials, including stainless steel, to meet the demands of different applications.
Hex nuts are the most commonly used, providing a strong and reliable fastening solution, while lock nuts prevent loosening under vibration. Cap nuts are designed to cover exposed threads, providing a clean finish and protection against corrosion. For more details on thread sizes and materials, check out our Metric Nuts page.

Metric Threaded Rod
Metric threaded rods are long rods with threads running along their entire length. These rods are used in construction, mounting systems, and hanging systems. They provide a versatile solution for creating adjustable lengths and securing heavy-duty assemblies. Whether you’re working on structural frameworks or mounting machinery, threaded rods offer flexibility and strength for various applications.
Our metric threaded rods are available in different lengths and thread pitches, allowing you to find the perfect fit for your needs. We also offer a wide range of strength grades and provide recommendations for compatible nuts and washers. For more information on lengths and specifications, visit our Metric Threaded Rod page.

Metric Head Cap Screws
Metric head cap screws are fasteners with a hexagonal head and a fully threaded shaft. They are commonly used in construction, automotive, and heavy machinery applications. These screws offer high strength and can be used in high-stress environments that require secure fastening.
We offer both hex head and button head types, giving you options for different aesthetic preferences and space constraints. Available in various sizes and threading options, these screws provide a reliable solution for numerous industrial applications.

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.
I love marsh fasteners!! Kathy and her grandson are the nicest people you will ever meet!! Kathy and Chris were my old bosses. Kathy is the best.
This is a great company to buy stainless steel fasteners from. Fast service, quality products, and competitive pricing. Don’t waste your time at the Big Orange or Big Blue box stores.
