The Washer Styles

You can find many washer styles available at the home improvement centers. There are six basic types of washers today: the flat, shoulder, tab, lock, countersunk and spring. These types have a few specialty styles to work on.

  • The Flat Washer. This is the most common type that includes a large number of washer configurations. You can see this in thin, flat and circular style with a hole in the center. This is actually for general-purpose works. The shapes will vary depending on the function of the washer.
  • Shoulder Washers. This type is also known as a step or flange washers with an integral cylindrical sleeve. The shape gives them the appearance of a low-crowned top hat. This style is useful and designed to mate with a cutout. This can also segregate the fastener from the material it works on. These washers work as insulators in the electronic equipment industry.
  • Tab Washers. This is usually round in shape and often manufactured with a single and many tab notches. This lock washer forms to shape around bolts or nuts or designed to lay flat. This type is ideal for use in harsh environments. This can lock parts into place in with extreme heat or heavy vibrations.

It has a split coil that bites into the head of the fastener and against another flat surface. This can work along with a flat washer to distribute an even load without deforming the assembly.
  • Countersunk Washers. These are the finishing washers that captures the head of the fastener. The countersunk provides a flush surface and are available in several shapes. You can find this type on some of the consumer products.
  • Spring Washers. This is also known as a disc washer. This type compress with a proportionate resistance to return to their pre-deflected shape. Use this washer for applications that need a part to take up play and maintain assembly tension. This can also compensate for expansion or contraction in materials.
