Providing Custom Pin Solutions Since 1977
Lone Star Industrial was founded in 1977 by brothers Bob and Ralph Navar. Together they were able to foresee the need for testing equipment, to include fixtures, in the wire harness industry. Lone Star Industrial (LSI) began making Spring Test Probes to fit specialized fixtures. LSI has continued to adapt to the needs of the wiring harness manufacturing industry with innovative and redefined products.
How It Works
Seated terminals allow for contact between the terminal and spring test probe at the correct depth.
Non-seated terminals will not allow proper connection between a terminal and spring test probe.
