3M 7100039192 Threadlocker TL42 Blue 250 Ml

Product Description

The 3M 7100039192 is a medium-strength, general-purpose threadlocker designed to secure threaded fasteners against loosening caused by vibration, shock, and corrosion. Sold in a 250 mL bottle, this blue-formula product cures on metal fasteners to create a controlled-strength bond that remains removable with standard hand tools. It is well suited for maintenance technicians, field service pros, and contractors who need a reliable threadlocker for routine fastener applications across HVAC, plumbing, electrical, and general mechanical work.

This threadlocker is appropriate for use on metal threaded assemblies in both residential and light commercial settings. Typical applications include securing bolts, screws, and studs on equipment panels, brackets, pump housings, and similar assemblies where periodic disassembly is expected. The medium-torque breakaway strength makes it practical for components that require regular service access without the need for heat or impact tools during removal.

Installation Notes

Application is typically performed by maintenance technicians, HVAC installers, plumbers, or electricians during equipment assembly or service. Clean and degrease threads before applying to ensure proper cure and bond strength. Apply a small amount directly to the fastener threads and assemble immediately. Allow adequate cure time before returning the assembly to service per the manufacturer's cure schedule.
