How do I choose a washer for a bolt?
The size of a washer indicates the size bolt that it fits, so you will choose your washer hardware to match the diameter of the fastener you selected. An exception would be Fender Washers. By design, these allow you to select from two size options (i.e. 1/4 x 3/4).
What are C washers used for?
C-washers are designed to slide in and out of position on a bolt or shaft in a partially completed assembly. They can also be used as a retention device on a grooved shaft to keep components in place.
What do different washers do?
Unlike flat washers, which are placed on both the bolt and nut side, spring washers only go on the nut side of the fastener to establish a bond. A spring washer offers axial flexibility that’s intended to prevent loosening of the fastener with which it’s paired.
Are there different grades of washers?
Grades: Flat washers do not have a specific grade as traditional fasteners such as Grade 5 or Grade 8 bolts do however there are two common types of steel used. Standard steel flat washers (low carbon steel) are not rated for hardness. Hardened steel flat washers.
When should you use spring washers?
For most applications, plain washers are typically used. For machines and objects that vibrate, spring washers are recommended. Spring washers are unique because they provide an axial load that counters vibrations and, thus, prevents fasteners from loosening.
When should you use a flat washer?
Flat washers prevent sinking of bearing surfaces
This is especially crucial if the contact area between a screw’s bearing surface and the object being fastened is small when fastening to a slot, for instance, or if the object being fastened is made of soft material such as aluminum or resin.

What is the difference between Type A and Type B washers?
Type A is a series of steel washers with broad tolerances, where precision is NOT critical. Type B is a series of flat washers with tighter tolerances where outside diameters are categorized as Narrow, Regular or Wide for specific bolt sizes.
