The ND INDUSTRIES 13110 is a permanent-strength anaerobic thread sealant and threadlocker designed to lock and seal threaded fasteners in mechanical assemblies. Applied as a liquid to fastener threads before assembly, it cures in the absence of air to form a rigid bond that resists loosening from shock and vibration. The 13110 outperforms mechanical locking devices such as lock washers and bevel washers by filling thread voids entirely, preventing micro-movement that leads to fastener backout. It also stops leakage through threaded connections and eliminates rust-lock by sealing out moisture. Packaged in a 10 ml bottle for bench or field use.
This threadlocker is suited for residential and commercial maintenance applications across HVAC, plumbing, electrical, and general mechanical trades. It is appropriate for use on small to medium fasteners where a permanent, non-removable bond is required. Technicians reach for permanent-grade threadlockers when fastener joints are not expected to be disassembled during the service life of the equipment, such as motor mounts, compressor hardware, and structural fastener assemblies.
Designed as a permanent-strength anaerobic threadlocker suitable for standard metal threaded fastener assemblies across HVAC, plumbing, electrical, and industrial mechanical applications.
Applied by licensed mechanics, HVAC technicians, plumbers, and electricians as part of fastener assembly procedures. De-energize or shut down all equipment before servicing fastened joints. Clean fastener threads of oil, grease, and old thread compound before applying; contaminated surfaces reduce cure strength. Permanent-grade threadlocker requires heat or mechanical breaking force for disassembly — confirm the correct grade before application on serviceable joints.
