SI® Solid Body Press-In Insert
Superior Threaded Connections in Plastics Applications
Creating reliable threaded connections in plastic components demands a fastener that delivers on both pullout strength and torque resistance without complex installation requirements. The new SI® Solid Body Press-In Insert with Retention Fin Design provides exceptional performance where it’s needed most.
This non-slotted, cold press insert features an innovative approach that outperforms standard press-in inserts – creating strong, reusable threads without requiring heat or ultrasonics for installation.
Exceptional Performance from Unique Retention Fin Design
The SI® Solid Body Press-In Insert delivers exceptional performance metrics that provide secure connections in your most demanding applications:
- Retention Fin/Barbed Feature provides significantly better pullout performance than other solid body press-in inserts on the market
- Pullout values in ABS plastic reaching up to 142 lbs. for larger sizes
- Torque-out values exceeding 36 in. lbs.
Versatility Across Industries and Applications
The SI® Solid Body Press-In Insert excels in harder plastics, including most thermoset resins, making it ideal for diverse applications across multiple industries.
