Commercial Flat Washers


Washers play critical roles in a variety of fastener applications. They are commonly placed between bolts, nuts, and fastened materials. They provide many benefits, including vibration absorption, extra spacing, and surface protection. Washers also increase the load-bearing capabilities of the fastened area, adding strength and stability to the application. Trio Fasteners supplies washers in an extensive selection of styles, sizes, materials, and finishes to suit a variety of industrial and commercial projects and assemblies.

Types of Metal Washers

Trio Fasteners offers high-quality metal washers for a range of industrial projects. Read below for more information about our inventory of washers.

Fender Washers

Fender washers, or sign washers, are recognized for their large, flat surface area and proportionally small internal holes. Their large surfaces significantly increase their load-bearing capabilities, distributing force evenly across fastened surfaces and under bolts or nuts. Fender washers are popular for automotive, plumbing, and electrical applications for even weight distributions.

Lock Washers

Lock washers, or split lock washers, are named for their ability to “lock” fasteners in place. They prevent bolts and nuts from twisting, turning, slipping, or loosening, greatly increasing the strength and reliability of a fastener installation. Lock washers are highly resistant to vibration, making them common for use in transportation or automotive applications.

Plate Washers

Plate washers are a type of flat washer with large surface areas and elevated load-bearing properties. Trio Fasteners supplies plate washers in both round and square styles. These washers are useful for limiting vibrations and resisting fastener movements. Their weight-distribution capabilities make them ideal for wood construction, marine applications, or projects where vibration is present.

SAE Flat Washers

SAE flat washers (Society of Automotive Engineers) are flat, thin, and small for their common use in automotive applications. Their highly flat composition is beneficial for tight fits in high-strength applications. Trio Fasteners provides SAE washers for automotive, aerospace, and transportation assemblies.

USS Flat Washers

USS flat washers (United States Standard) are flat and thin, featuring larger outer diameters to aid in even distributions of force and weight. They help prevent abrasion and offer extra protection to fastened materials and surfaces. USS flat washers are utilized for industrial, manufacturing, and repair applications across a variety of trades.

Materials for Washers

Trio Fasteners supplies washers in a variety of materials to suit unique application requirements.

Stainless Steel

Stainless steel (SS) washers from Trio Fasteners are offered in 316 SS and 18-8 SS. The composition of stainless steel washers aids in corrosion resistance while increasing durability and strength. Stainless steel washers can be used for internal or external applications, helping to retain stable fastener connections.

Steel

Washers are also available in various steel alloys, including Grade 2, Grade 5, and Grade 8. Grade 2 alloys are considered low-carbon, while Grade 5 and Grade 8 alloys are rated as medium-carbon. Increased carbon content strengthens the steel, allowing higher grades of washers to be used in more demanding environments. Low-carbon alloys are better suited to minimal or low-strength applications and, as such, provide a more cost-effective solution.

Additional Materials

Trio Fasteners offers additional materials for specialty uses. Materials include brass, nylon, silicone bronze, aluminum, titanium, and Monel. Washers of these materials fulfill unique services and are less common than stainless steel or steel. Talk to a specialist today for help determining the right material for your needs.

Finishes for Metal Washers

The finish of a washer offers additional advantages, such as increased corrosion resistance, enhanced durability, or greater temperature tolerances. Finishes can include:
  • Zinc
  • Zinc-Yellow
  • Plain
  • Hot-Dip Galvanizing (HDG)
