Slotted Nuts

Slotted nuts, also referred to as slotted hex nuts or castellated nuts, have grooved heads with holes that allow for insertion of pins, which will lock the nut in place. Slotted hex nuts are commonly used in automotive assemblies or machine settings to ensure that the components are staying in place, or for general purpose fastening and locking. Aetna Screw designs and manufactures slotted nuts in a wide range of materials, thread sizes, hardnesses, and specifications for your application.
