260-M4-RS-CR

Overview

The E-Z LOK 260-M4-RS-CR is a press-in threaded insert designed for plastic substrates. It features an M4-0.7 metric thread size and a reverse slot configuration to enhance retention within the host material. The component utilizes stainless steel threads for corrosion resistance and durability. Installation is performed via cold press-in methods, eliminating the need for heat or adhesives. The unit is supplied in packs of five.

Feature Summary

• Reverse slot design provides enhanced mechanical retention within thermoplastic and thermoset materials
• Stainless steel internal threading ensures long-term corrosion resistance and structural integrity
• Cold installation process reduces molding costs and eliminates post-molding thread chasing

Applications

• Insertion into thermoplastic components requiring high-strength fastening points
• Assembly of thermoset plastic housings where thermal damage must be avoided
• Precision electronic enclosures needing reliable threaded mounting locations

Procurement Notes

Verify the specific reverse slot designation (RS) against standard straight-slot variants to ensure compatibility with the intended plastic substrate geometry. Confirm that the M4-0.7 thread pitch matches the mating hardware requirements. Ensure the purchasing documentation explicitly references the CR suffix for the correct stainless steel material specification and packaging quantity.

Selection Notes

Select this model when superior pull-out strength is required compared to standard inserts due to the reverse slot geometry. It is suitable for applications involving vibration where standard smooth-wall inserts might loosen. Choose this variant over heated inserts if the base plastic has a low melting point or cannot withstand thermal processing during installation.

Part Context

This component belongs to the E-Z Press series of press-in threaded inserts manufactured by E-Z LOK. These inserts are engineered specifically for integration into plastic parts during manufacturing. The series offers various thread sizes and configurations to accommodate different material types and load requirements in industrial assembly contexts.

Replacement Considerations

Direct substitutes include other E-Z LOK M4-0.7 reverse slot inserts such as 260-M4-RS-SS if material specifications differ. Verify dimensional compatibility with existing tooling before switching brands. Cross-referencing with generic M4 inserts requires careful validation of the reverse slot retention mechanism.
