1, High tchemical resistance
2, No on-torque adjustments needed
3, Act as a thread lubricant 

Lock nuts and bolts against vibration and thermal expansion.

Suitable for all shapes and sizes of fasteners.

Maintain critical adjustments of the assembly.

No on-torque adjustments needed.

FL thread lockers are single-component adhesives that cure in the absence of air 

and in contact with active metal to form a tough thermoset plastic. They completely 

fill all voids between the interfacing threads, which makes the assembly an unitized 

component, prevents any movement between threads, and ultimately prevents loosening.

FLthread lockers is thread sealing. This property is especially important when assembling through-bolts in an oil reservoir or cooling jacket in order to keep the fluids sealed in and corrosion out. 

Examples of this application are common but not limited, to gearboxes and internal combustion engines.

Reliable assembly:

• Not only locks against vibration, 

shock and thermal cycling but also seals against corrosion and galling

Easy disassembly 

• Using hand tools when low or medium grade formula is selected

Out perform locking devices:

• Better clamp load retention compared to all mechanical locking devices 

•  Reliable threaded assemblies reduces costly

• “One size fits all”, universally applicable for a wide range of fastener sizes
Processing: 
•  Ease of automation reduces assembly costs and  increases throughput
Material Cost:
•  Lower cost per unit compared to most locking devices

Applications:

Application Methods

Pre-Dispensed: 

 •  FL sticks semisolid formula can be applied before hand on bolts that are waiting to be assembled

Pre-Assembly:  

 •  FL liquid threadlockers are designed to be applied at the moment that parts will be assembled

Post-Assembly:  

•  FL wicking grade formula can be applied on parts that are already assembled
