These economical, easily installed retainers are ideal for the many applications where it is necessary to position and securely retain a bolt or screw until a nut is applied at a later stage to complete the assembly.
When a nut is applied and tightened down,the teeth on the retainer set up a strut action that resists any loosening or back-off rotation.
Bolt Retainers are easily installed with a standard nutsetter (magnetic if desired), or with a simple, easily made, push-on tool.
