Washer fastener, also known as railroad washers, is a common and relatively small fastener, but it is an important component that ensures railroads’ safe and efficient operation. In railways, it is usually used together with rail bolts and rail nuts, installed between the bolt and nut to securely fasten the rail to the sleeper, ensuring the safety of the railway. In addition, many railway fasteners require them to secure the railway system, such as rail joints, tie plates, rail clips, etc. AGICO supplies different types and models of washer fasteners, including AREMA 1967 Lock Washer, Flat Washer, E.D. Washer (Double Coil Spring Washers). Washer fasteners are usually flat metal rings with a hole in the center. E.D. Washer, also known as Double Coil Spring Washers, is spring-shaped. Washer fasteners can distribute the pressure of bolts and nuts over a larger area, preventing rail components from breaking due to excessive pressure. They also increase the friction between the washer fastener and other elements, making the fastening stronger and preventing the loosening of fasteners caused by vibrations from train operations.
AGICO provides a variety of materials and specifications of washer fasteners to meet the diverse requirements of customers. We produce a large number of supporting products, such as rail bolts, rail nuts, rail fish plates, rail clips, etc., to achieve a one-stop service. We also source high-quality raw materials from reliable suppliers, such as Carbon Steel, Stainless Steel, Q235, Copper, Iron, etc. AGICO has established a comprehensive quality monitoring system, and our team carefully inspects and supervises the washer fasteners to ensure that all our products meet international quality standards and the latest market trends.
Hot-Selling Railroad Washers
AREMA 1967 Lock Washer
AREMA 1967 Lock Washer is a high-strength washer specifically designed for the railway industry, conforming to the 1967 standards of the American Railway Engineering and Maintenance-of-Way Association. Unlike ordinary washers, AREMA 1967 Lock Washers feature a wedge or cut design that provides an anti-loosening function. When the rail bolts and rail nuts are tightened, the AREMA 1967 Lock Washer applies a reverse force or friction, preventing the bolts and nuts from loosening under conditions of vibration, thermal expansion contraction, or impact. AREMA 1967 Lock Washers offer superior anti-loosening effects, effectively enhancing the safety and reliability of the tracks.

Flat Washer
Flat washers are flat, ring-shaped components with a hole in the center, and are also used in conjunction with bolts and nuts. They are relatively simple and practical. Flat washers are widely used in railway systems, mechanical equipment, and everyday items. They can adjust the gap between components, prevent direct contact between fasteners and the surface of the connected parts, and protect fasteners from damage, thereby extending the service life of the fasteners. The production cost of flat washers is relatively low, making them an economical choice for projects that require a large number of railroad washers.
E.D. Washer
E.D. washer, also known as elastic double washer, double coil spring washers, or double coil elastic washers, is a specially designed railroad washer with a dual spiral coil structure. Compared to other railroad washers, the E.D. washer provides greater elasticity and locking effect. It offers stronger spring force when compressed, making it better able to resist the vibrations generated during high-speed train operations.
Advantages of Washer Fastener
Anti-loosening
Washer fasteners all have anti-loosening functions. Through their special structures, such as wedges or cuts, they can continuously increase the reverse force after bolts or nuts are tightened, effectively preventing fasteners from loosening. They also serve to cushion and distribute pressure, ensuring that bolts and nuts maintain stable tightening force over long-term use.
Stress Distribution
Washer fasteners can evenly distribute the stress applied when bolts and nuts are tightened over a larger area, thereby reducing localized stress concentration. The distribution of stress helps prevent bolts and nuts from cracking due to excessive fatigue during use. This can effectively extend the service life of fastening components, thereby reducing maintenance costs.
Easy Installation and Maintenance
Washer fasteners not only have a simple structure but are also easy to install. The installation process does not require complex tools or techniques, making them particularly advantageous in projects with frequent installations or large workloads, as they can reduce labor and workload, thereby improving efficiency. Additionally, they have low maintenance costs.
Low Cost
Washer fasteners have a low manufacturing cost, but they offer multiple functions, such as preventing loosening, securing fasteners, and improving stability. Due to their simple structure, maintenance is also convenient and quick, reducing labor costs. With washer fasteners, friction and damage between components can be minimized, thereby reducing maintenance costs.
Applications of Washer Fastener
RAILWAY SYSTEM
Railroad washers are used in railway systems to prevent bolts and nuts from loosening, ensuring the stability of the rails.
CONSTRUCTION ENGINEERING
In wood connections and concrete anchoring, washers can prevent bolts from penetrating or damaging the wood and avoid damage caused by bolts over-compressing the concrete surface.
AUTOMOTIVE INDUSTRY
Washers are used in engine blocks, cylinder heads, and other areas to ensure that bolt connections remain secure under high temperature and pressure conditions. They also help prevent components from loosening due to vehicle vibrations.
