3. Angle and Thread Pitch Errors

4. Distributes Load More Evenly

5. Advantages of Threaded Inserts Low cost Blind installation Permanent, reliable fastening Eliminates the need for welding or tapping

6. Most Common Threaded Inserts Coil Type Wire wound into a helical coil Larger diameter than tapped hole— applies compression Can be self- threading or drilled and tapped

7. Rivet Type Can be installed blind Can be used on sheet metal and fiberglass Cheaper and easier than welded studs for non-permanent applications
