Titanium Threaded Inserts vs Tapped Holes
A directly tapped hole is simple and compact, while a threaded insert can provide a replaceable female thread, repair path or defined wear interface. The better choice depends on parent material, wall, edge distance, cycles, load and maintenance.
Comparison
| Decision | Threaded insert | Tapped hole |
|---|---|---|
| Serviceability | Insert may be replaceable if installation system permits | Damage affects the parent component |
| Space | Requires prepared hole and external body | Uses the parent wall directly |
| Locking | Mechanical keys, interference or approved compound | Thread locking handled at fastener interface |
| Inspection | Insert plus installed position and parent interface | Finished internal thread and parent integrity |
Selection Point
Use an insert only after checking parent strength, radial wall, edge distance, installation access, galvanic exposure, torque, axial load and repeated assembly. Define both internal and external threads and their classes.

FAQ
Does an insert always increase thread strength?
No. Capacity depends on insert geometry, parent material, wall, engagement, installation and load direction.
Can inserts repair stripped threads?
Some systems can, provided sufficient sound parent material remains and the approved repair drawing controls hole preparation and acceptance.
