Professional Applications & Engineering Value

This brass press fit insert is engineered to solve the common challenge of creating durable, high-strength threaded points in plastic applications where traditional threading methods fail. Its ultra fine 3/16"-100 UNS thread and Class 3B precision fit provide exceptional resistance to loosening under vibration, a critical requirement in automotive, electronics, and consumer goods assembly. The press-fit installation eliminates the need for adhesives or heat-staking, streamlining production and reducing assembly time. The robust 50,000 psi tensile strength ensures the insert can withstand repeated disassembly and reassembly cycles, making it an ideal, long-lasting solution for maintenance panels, housings, and other structural plastic components.
