Tech Notes on Tinnerman Fasteners

Tinnerman speed nuts are self-locking steel fasteners. Locking action is derived from force exerted by two arched prongs against the root of the screw thread and by the spring ten- sion of the prongs and base. The combined forces of the thread lock and spring tension provide a vibration proof fastening. Speed nuts retain their spring tension & may be used repeatedly without losing their self-locking effectiveness. They are suitable for numerous non-structural applications.  Standard finish is phosphate-coated with three coats of olive drab paint.

 

IMPORTANT

Speed nuts for aircraft are designed to fit type B (blunt) sheet metal screws only. Do not use pointed type A sheet metal screws with aircraft speed nuts. There is a difference in root diameter and thread pitch.  To be certain the fastener prongs grip on the full root diameter, the screw should protrude two to three threads beyond the prongs.
