Nuts TRIZ Cases

A segmented nut uses a rotating sleeve to release segments for quick removal.

Segmented collar sections distribute clamping force to prevent chipping damage during bolt installation.

Interior die slots in the insert repair damaged fastener threads, preventing backing out and maintaining thread integrity without increasing torque.

Deformation elements transmit perpendicular forces to fasten the insert into a slab recess, eliminating cumbersome assembly operations.

Partial toothing on anchor rail free legs engages locking elements securely, resolving stability loss during fastening and repositioning.

A magnetic and threaded attachment system secures a treatment member to a shaft using detents and spring-biased balls.

Merging the driver and adjustment components into one unit eliminates separate assembly steps while maintaining reliable tolerance compensation.

Protrusions on the helical thread compress material to prevent fastener backout in thin metal and wood joints.

A removable plastic insert seats within a fastener head recess to provide direct tool access, preventing damage during removal from coated surfaces.

Segmented threaded rods and bearing collars enable accessory attachment without drilling holes that compromise sheet tightness.

Fourier series optimized conical screw threads create surface contact to distribute load and reduce plastic deformation.

Segmented filling members with female threads allow technicians to extract components from counterbores, resolving repair difficulties.

A curable mounting dome hardens on a component to form a stable structure for fastener insertion, eliminating complex surface preparation steps.

Segmenting the rivet portion with axial slits reduces joining load while preventing rotation and boosting connection strength.

Spring elements bias the anchoring element against flanges, preventing disengagement and ensuring stable engagement.

A separation fastener assembly uses a sleeve-shaped retaining element to hold the nut in place during normal operation.

A one-piece metal insert uses a radially pushed bottom wall to close the longitudinal passage after tapping.

A fastening element uses a through-opening engagement means to transmit torque from a setting bit.
