Order LookupLock Washers
Available96 products
Lock washers create tension by “locking” the bolt or screw into the workpiece’s threaded hole. Unlike flat washers, they have serrations on the washer body to prevent rotation and provide a more secure connection than flat washers. These washers are frequently used in high-vibration environments to prevent the loosening of the fastener assembly.
Material
Split Lock Washers
Split lock washers, also known as spring lock washers, have a spring action that creates resistance against vibration. They have an opening where one side gradually rises above the other that compresses while simultaneously pushing against the mating surfaces. They are often used with softer materials and do not provide as much resistance to loosening in harder materials.

Curved Split Lock Washers
Curved split lock washers have a wavy shape for use with right- and left-hand bolted joints and are more vibration-resistant than split lock washers in treated lumber applications. These washers compress as the fastener is tightened to prevent movement-induced loosening in treated lumber applications.

External Tooth Lock Washers
These washers have teeth around their outer diameter to tightly grip into the work surface for greater hold than internal tooth washers. External tooth washers work well with larger bolt or screw heads.

Internal Tooth Lock Washers
Internal tooth lock washers absorb shock and minimize vibration to stop nuts or bolt heads from loosening. These washers are used in electrical applications where they scrape the surface of the surrounding area to improve the electrical connection.

Serrated Lock Washers
These washers have indentations on their surface that bite both into the fastener head and the contact surface to create maximum holding power. The increase in friction force prevents the fastener from coming loose. Serrated lock washers work well on soft materials.
