Fastening Washers
The purpose of a washer is to distribute the pressure of the nut evenly over the surface so that the surface isn’t damaged and to ensure that the nut is pressed against a smooth surface. The purpose of a lock washer is to prevent a threaded fastener from loosening over time. System 22, Inc. stocks and manufactures a wide variety of flat and lock washers in standard and exotic materials.

Belleville Spring Lock Washers
Belleville spring lock washers are specialized washers designed to provide high spring tension and compensate for bolt loosening caused by vibration or thermal expansion. These conical washers apply a constant load, maintaining bolt tension and preventing fastener fatigue. Discover how Belleville spring lock washers enhance joint integrity and reliability in critical applications such as aerospace, automotive, and heavy machinery.
Black Oxide Washers
Black oxide washers are metal washers treated with a chemical process to achieve a dark, corrosion-resistant finish. This finish not only enhances the appearance of the washer but also provides added protection against rust and wear. Explore how black oxide washers offer durability and aesthetic appeal, making them ideal for use in automotive, industrial, and decorative applications.
Brass Washers
Brass washers are versatile fasteners known for their corrosion resistance, electrical conductivity, and aesthetic appeal. These washers are commonly used in electrical and plumbing applications, where non-magnetic and non-sparking properties are essential. Learn how brass washers provide reliable sealing and conductivity in various environments, making them a preferred choice for both functional and decorative purposes.
External Tooth Lock Washers
External tooth lock washers feature teeth or serrations on the outer circumference, providing enhanced grip and preventing loosening of fasteners due to vibration. These washers are used in applications where secure locking is crucial, such as automotive assemblies and machinery. Explore how external tooth lock washers ensure reliable fastening and improved joint integrity in demanding environments.
Flat Washers
Flat washers, also known as plain washers, are essential components used to distribute load and prevent damage to surfaces under fasteners. These simple, flat-shaped washers provide a smooth bearing surface and help to reduce friction between the nut or bolt head and the substrate. Discover the versatility and importance of flat washers in various industries, where they play a critical role in improving fastener performance and stability.
Internal Tooth Lock Washers
Internal tooth lock washers feature internal serrations that bite into the fastener and substrate, preventing loosening caused by vibration or torque. These washers offer a secure locking mechanism and are commonly used in applications where external aesthetics are important, as they do not protrude beyond the fastener head. Learn how internal tooth lock washers ensure reliable fastening and increased joint integrity in assemblies subjected to dynamic loads.
Spherical Washers
Spherical washers, also known as conical washers or Belleville washers, have a unique shape that allows them to compensate for angular misalignment and absorb shock or vibration. These washers are used in applications requiring flexibility and load distribution, such as automotive suspensions and heavy machinery. Explore how spherical washers improve joint performance and extend the lifespan of assemblies by reducing stress concentrations.
Split Lock Washers
Split lock washers, also called helical spring washers, feature a split design that creates spring-like tension when compressed between the fastener and the substrate. These washers prevent loosening caused by vibration and thermal cycling, providing a reliable locking mechanism. Discover how split lock washers enhance joint integrity and security in critical applications, ensuring optimal performance and safety.
Square Beveled Washers
Square beveled washers are specialized washers with a square shape and beveled edges, designed to provide a flat bearing surface and distribute load evenly under fasteners. These washers are commonly used in structural applications where alignment and stability are critical. Learn how square beveled washers improve the strength and durability of connections, particularly in timber framing and heavy construction projects.
Spring Washers
Spring washers, also known as disc springs or Belleville washers, are used to apply a flexible, controlled load to fasteners, compensating for thermal expansion and vibration. These washers maintain tension and prevent loosening, ensuring a secure joint in dynamic environments. Explore how spring washers enhance the reliability and longevity of assemblies subjected to varying loads and conditions.
