Spring Washer Overview
Spring washers often referred to as a lock washer or split washers are designed to keep bolted or screwed connections tight by locking the head of a bolt or nut to the substrate using friction. The split in the spring washer absorbs the initial driving torque and visually closes under normal bolt tightening. The compensating spring force of the spring washer trying to 'spring' back into its stamped helical shape keeps constant tension on the nut and prevents any movement when under vibration. Spring lock washers provide resistance against the removal rotation of the bolt, helping it to stay in place and apply constant pressure to the bolt to prevent loosening. A spring washer should be used under the nut side of the connection.
If you need to also use a plain flat washer in conjunction with a spring washer, the spring washer should always be positioned directly next to the nut. Spring washers can also be used in conjunction with nyloc lock nuts for maximum protection against vibration, this is very common in automotive applications.
