260-4-RS-CR

Overview

The E-Z LOK 260-4-RS-CR is a press-in threaded insert designed for installation in thermoset and thermoplastic materials. It features a 1/4-20 UNC internal thread standard and is constructed from Grade 303 stainless steel with a silver finish. The component has an overall length of 0.5000 inches, a head diameter of 0.3750 inches, and requires a 5/16-inch drill size for the pilot hole. This reverse slot style allows for tool-free press-in installation.

Feature Summary

• Reverse slot design facilitates secure retention within plastic substrates
• Tool-free press-in installation method eliminates need for specialized equipment
• Grade 303 stainless steel construction provides corrosion resistance
• Compatible with both thermoset and thermoplastic molding applications

Applications

• Post-molding installation in thermoset plastics
• Post-molding installation in thermoplastics
• Creating reinforced threaded holes in plastic enclosures
• Hardware attachment points in plastic assemblies

Procurement Notes

Verify that the specified model number matches the required thread standard and material grade. Confirm the host material compatibility with the reverse slot design before procurement. Ensure the available space accommodates the 0.5000-inch overall length and 0.3750-inch head diameter. Check for any specific surface finish requirements beyond the standard silver coating.

Selection Notes

Select this part when a durable, corrosion-resistant threaded insert is needed for plastic components. The Grade 303 stainless steel offers better corrosion resistance than standard carbon steel options. The reverse slot style is specifically engineered for high pull-out strength in plastic materials compared to smooth inserts. Consider the 1/4-20 thread size for standard hardware compatibility.

Part Context

This component belongs to the E-Z Lok E-Z Press series of threaded inserts. These inserts are distinct from self-tapping or heat-set types as they are designed for post-molding installation. The series includes various thread sizes and styles, with the reverse slot variant offering enhanced mechanical locking capabilities in plastic substrates.

Replacement Considerations

Direct substitutes include other E-Z Lok 1/4-20 reverse slot inserts such as 260-4-BR (brass) or 260-4-CR-PK5 (kit). Verify that alternative brands match the 0.5000-inch length and 5/16-inch drill size requirements to ensure proper fitment in existing tooling.
