Self-Clinching Self-Locking Nuts
Description
Self-clinching self-locking nuts provide a permanent, prevailing-torque locking thread in thin sheet materials. Installed by pressing, the fastener becomes captive in the panel and offers reliable resistance to loosening under vibration and repeated service conditions.
Features
- Prevailing-torque locking thread for vibration resistance
- Permanent installation in thin sheet using standard pressing methods
- Unified and Metric thread forms
- Material options: heat treated steel, stainless steel (300 series), and aluminium (7076-T6)
- Typical finishes include black dry film lubricant and uncoated (none), depending on material
