T-SERT®
T-Sert® Self-Locking Insert
Additional joint strength in low tensile materials
Self-locking internal threads
Wear-resistant internal threads in soft materials
T-Sert® inserts require no locking rings or other separate locking devices. An integral, self-locking element extends longitudinally through the wall of the insert, and provides simultaneous locking action for both internal and external threads in accordance with MIL- I-45932. The torque developed by the T-Sert locking element provides approximately twice as much torque on the external as on the internal diameter, precluding the possibility of unintentional rotation after installation.
Economical
Because of inherent simplicity of design, T-Sert inserts cost substantially less than all other types of solid wall, self-locking inserts. And with easy installation the installed cost of T-Sert inserts is less than that of all other inserts; particularly wire-type inserts. Either-end installation means that T-Sert inserts can be installed more quickly than other insert types since they do not have to be oriented, permitting additional economy in time-saving. All this makes T-Sert inserts the most economical insert available.
Reusable
T-Sert inserts internal thread lock can be reused a minimum of fifteen times. Extremely low cold flow and exceptional memory in the T-Sert locking element assures reusability that meets the requirements of MIL-I-45932.
High Strength
One piece, solid wall construction gives T-Sert inserts the ultimate in both torque and tensile strength.
Excellent Corrosion Protection
T-Sert inserts do not break the surface coating on the parent material as do key, ring, swage-locked or self-tapping inserts.
Easier, Quicker To Install
T-Serts inserts require no special hole preparation, no special counterbores, tapes or gages, no indexing or referencing operations. The inserts are installed by utilizing the internal thread of the insert and a simple driving tool. And, because they do not require a swaging or ramming home of keys or rings, T-Sert inserts cause no undue stresses due to installation.
