LOCTITE 262 is a high-strength threadlocker used by composite and equipment manufacturers to permanently secure bolted and threaded metal connections against vibration loosening. For FRP factories, pultrusion lines, and equipment assembly operations that need a robust, high-strength threadlocking solution, LOCTITE 262 is formulated to cure reliably on metal threads.
Typical Properties of LOCTITE 262
Buyers evaluating this high-strength threadlocker for a new sourcing relationship should reference the physical properties listed below alongside the current Safety Data Sheet before specifying it into an assembly procedure.
| Property | Typical Value |
|---|---|
| Specific Gravity @ 25°C | 1.1 |
| Flash Point | See SDS |
| Viscosity, Brookfield RVT @ 25°C (Spindle 3, 20 rpm, Helipath) | 1,200 to 2,400 mPa·s |
| Viscosity, EN 12092-MV @ 25°C, after 180 s (Shear rate 129 s⁻¹) | 400 mPa·s |
How LOCTITE 262 Is Applied for Assembly
For best results, all surfaces should be cleaned with a LOCTITE cleaning solvent and allowed to dry before application. If the material is an inactive metal or cure speed is too slow, all threads should be sprayed with activator and allowed to dry. It should be shaken thoroughly before use, and the applicator tip should not touch metal surfaces during application to prevent clogging.
For thru holes, several drops are applied onto the bolt at the nut engagement area. For blind holes, several drops are applied down the internal threads to the bottom of the hole. For sealing applications, a 360-degree bead is applied to the leading threads of the male fitting, leaving the first thread free, and the material is forced into the threads to fill voids; for bigger threads and voids, the amount is adjusted and a bead can also be applied to the female threads.
Disassembly and Clean-Up
Because this threadlocker is high-strength, disassembly requires localized heat applied to the nut or bolt to approximately 250°C, with the connection disassembled while hot. Cured product residue can be removed by soaking in a LOCTITE solvent combined with mechanical abrasion, such as a wire brush.
Why Sourcing Consistency Matters
Inconsistent threadlocker viscosity or cure behavior can lead to loose fasteners, rework, or assembly line delays across FRP pipe and tank, pultrusion, and equipment manufacturing operations. Buyers who source this product through a documented supply chain reduce the risk of receiving mismatched batches with inconsistent viscosity or cure speed.
Where to Source LOCTITE 262
Composite material buyers and assembly manufacturers can source this threadlocker and related auxiliary agent products through Thousands Technology’s supply chain resource support, which helps FRP factories, boat builders, and pultrusion manufacturers maintain consistent access to recommended international brand products. For handling and safety classification references used across manufacturing operations, buyers can also review ASTM standards and publications.
Documentation
Before specifying this product into a production process, buyers should request the current Technical Data Sheet and Safety Data Sheet to confirm viscosity, cure speed, and handling requirements for their specific fastener sizes.
Frequently Asked Questions
What is LOCTITE 262 used for?
It is used as a high-strength threadlocker to permanently secure bolted and threaded metal connections against vibration loosening in assembly operations.
Does LOCTITE 262 need an activator on inactive metals?
If the material is an inactive metal or cure speed is too slow, threads should be sprayed with activator and allowed to dry before applying the product.
How is a threaded connection disassembled after using LOCTITE 262?
Because it is high strength, localized heat of approximately 250°C is applied to the fastener, and the connection is disassembled while hot.
Where can I get technical support for sourcing LOCTITE 262?
Buyers can request the current TDS and SDS and reach out through Thousands Technology’s supply chain resource support for sourcing guidance on LOCTITE 262 and related assembly products.
