Loctite 232331 Threadlocker Retaining Compound

Product Description

The LOCTITE 232331 is a threadlocker and retaining compound designed to secure threaded fasteners and cylindrical assemblies against loosening caused by vibration and shock. Threadlockers in this category cure anaerobically, meaning they harden in the absence of air when confined between metal surfaces. The 232331 is used by mechanical contractors, industrial maintenance technicians, and assembly professionals working on equipment where fastener integrity is critical. At 1 pound, the package is suited for bench-stock or job-site use where repeated application is expected.

This compound is appropriate for a range of industrial and mechanical assembly applications, including securing bolts, studs, screws, and press-fit components in machinery, HVAC equipment, pump assemblies, and general mechanical systems. It is well-suited for both production environments and field service repairs where vibration-resistant fastening is required. Trade professionals working on rotating equipment, compressors, or structural mechanical joints commonly keep a threadlocker compound in their service inventory.

Key Features

• Anaerobic cure mechanism activates between metal surfaces without air exposure
• Resists loosening from vibration and dynamic shock loads
• Applicable to threaded fasteners and cylindrical retaining applications
• Single-package format suitable for bench stock or field use
• Lightweight at 1 pound for easy transport and storage

Compatibility

Designed as an OEM-style threadlocker and retaining compound for use on metal threaded and cylindrical assemblies in industrial and mechanical service applications.

Installation Notes

Application is typically performed by licensed mechanical technicians or qualified maintenance personnel. Surfaces should be clean, dry, and free of oils or contaminants before applying the compound. Ensure equipment is de-energized and depressurized before disassembly or fastener service. Allow adequate cure time before returning the assembly to service, per the product cure schedule.
