Beveled Washers – Purpose And Different Types

What are Beveled Washers?

Beveled Washers, also known as cupped spring washers, are distinguished by an uneven, angled shape. They are not as flat as some have a circular shape, giving them the appearance of washers in a drawer. Also, in some cases, one side of a beveled washer is slanted while the other is flat. The non-parallel faces can be mated and aligned with a stable and tight fit because the sloped side accommodates various installation angles.

The vast range of thicknesses available in malleable beveled washers makes them suitable for greater applications. Inevitably, the angle is decided by the washer’s span dimension and will be matched to the surface’s angle. Finding a washer with the tightest possible angle is critical.

Like flat washers, beveled washers are a fastening mechanism used with bolts. Washers with a beveled edge can be useful if two non-parallel surfaces are attached. Due to beveled washer technology, more complex cars, structures, bridges, and items are now conceivable. It’s important to think about all of these things when selecting a beveled washer for your project.

Purpose of Beveled Washers

Some of the purposes of beveled washers include:

  • Beveled washers distribute a load of fasteners to prevent damage to objects. Protecting objects from damage is made easier with beveled washers.
  • For structural beams, beveled washers may be necessary. A beveled washer must be used to fasten a slanted structural beam.
  • Beveled washers are frequently used in steel construction to ensure that fasteners are properly fitted and aligned in accordance with local building requirements.
  • The flanges of a normal steel beam are typically sloping. As required by rules, a beveled washer can be used to ensure that the head of a bolt is positioned perpendicular to the flange.
  • When using square or rectangular washers, it is easier to align the bevel with the fastener or surrounding item. Because spherical washers tend to revolve around the bolt, this construction style is less prone to cause problems.
  • Beveled washers are also often used in kitchen and bathroom sink faucets. These are frequently utilized in faucets with worn stem travel or broken sink seats.
  • Beveled washers are also used to seal water straight from the seat’s aperture rather than the margins around the seat.

Types of Beveled Washers

Some of the types of beveled washers are:

  • Square Beveled Washer – Stainless steel square beveled washers are commonly used in I-beam bolting because they fit the 2″ in 12″ beam profile. In square dimensions ranging from 1.25 to 3.00, these washers normally come in depths ranging from 0.34 to 0.81. Leveling and shimming can also be accomplished using beveled square beveled washers. Most fastening applications use parallel bearing surfaces to ensure that the fastening components sit flat and securely in the mated parts.

  • Hardened Beveled Washer – When mounting bolts through an I beam flanges, it is normal practice to utilize hardened bevel washers. These washers meet the F436 specification for hardened steel washers. Plain and galvanized are a couple of the finishes you will find for these washers.
  • Round Beveled Washer – There are round beveled washers available in a wide range of diameters, materials, and finishes, from steel to nylon and plain to tin.

A beveled washer also needs to be the right size for the fastener. The hole in the washer should be small enough to keep the fastener’s head from going through but big enough to let the bolt shaft go through easily. Users also have to think about the thickness of the washer and the steep angle before considering it.
