240-008-CR.250

Overview

The E-Z LOK 240-008-CR.250 is a press-in threaded insert designed for plastic substrates. It features an 8-32 thread size and measures 0.250 inches in length. Constructed from stainless steel, this flush-style insert provides high-strength threads in thermoset and thermoplastic materials. The component is engineered for demanding applications in automotive and aerospace industries, ensuring reliable fastening solutions.

Feature Summary

• Provides high-strength internal threading within plastic substrates
• Flush design ensures a low-profile finish after installation
• Stainless steel construction offers corrosion resistance
• Compatible with both thermoset and thermoplastic materials

Applications

• Automotive assembly requiring durable plastic mounting points
• Aerospace components utilizing thermoset or thermoplastic structures
• Electronics housings needing reinforced screw attachment points
• Industrial equipment assemblies involving plastic enclosures

Procurement Notes

Verify the specific material grade of the stainless steel against application requirements. Confirm that the substrate material is compatible with press-fit installation methods. Ensure the hole diameter matches the manufacturer's specifications for the 8-32 thread size to guarantee proper retention force. Check packaging quantities as these inserts are often sold in bulk packs rather than single units.

Selection Notes

Select this model when a flush surface finish is required after insertion. Choose stainless steel over brass or carbon steel if corrosion resistance is critical. This part is suitable for thermoplastics and thermosets but may not be appropriate for soft metals like aluminum where self-tapping alternatives might be preferred. Consider the 0.250-inch length relative to the wall thickness of the target plastic component.

Part Context

This insert belongs to the E-Z Press series, which utilizes mechanical interference fit for installation without heat or adhesives. It is distinct from knife-thread or solid-wall variants by its specific geometry optimized for plastic deformation during press-fitting. The product line focuses on creating permanent threaded connections in non-metallic materials.

Replacement Considerations

Direct substitutes must match the 8-32 thread pitch and 0.250-inch length. Verify that alternative brands offer stainless steel construction for equivalent corrosion performance. Ensure the replacement part is also designed for press-fit installation in plastics to maintain similar holding torque characteristics.
