Description
Permabond A1042 is a medium strength anaerobic threadlocker designed to lock and seal threaded metal fasteners, preventing loosening caused by vibration, shock and thermal cycling. Ideal for maintenance, manufacturing and engineering applications, it provides a reliable, serviceable bond while protecting threaded assemblies from corrosion and fluid leakage.
The adhesive cures rapidly when confined between close-fitting metal surfaces and in the absence of air, creating a durable polymer that resists movement and maintains clamp load over time. Once cured, Permabond A1042 helps extend the service life of machinery and equipment by reducing the risk of fasteners working loose during operation.
Unlike high-strength threadlockers that often require heat for removal, Permabond A1042 offers a medium-strength bond that can normally be dismantled using standard hand tools, making it an excellent choice for assemblies that require periodic maintenance or servicing.
Typical Applications
Permabond A1042 is suitable for securing threaded fasteners across a wide range of industries, including:
- Automotive assembly and repair
- Industrial machinery
- Pumps and compressors
- Electric motors
- Agricultural equipment
- Construction machinery
- Conveyor systems
- Gearboxes
- Hydraulic equipment
- General engineering
It is ideal for locking bolts, nuts, studs, grub screws and other threaded fasteners where resistance to vibration is essential.
Key Benefits
- Medium strength threadlocker for removable assemblies
- Prevents fasteners loosening due to vibration and shock
- Seals threads against moisture, corrosion and leakage
- Reduces maintenance and equipment downtime
- Suitable for most metal threaded fasteners
- Fast curing anaerobic formulation
- Can typically be removed using standard hand tools
- Supplied in a convenient 50ml bottle
Suitable Substrates
Permabond A1042 is designed for use on metal threaded components, including:
- Steel
- Stainless steel
- Aluminium
- Brass
- Cast iron
For inactive metals such as stainless steel, plated fasteners or zinc-coated components, the use of an anaerobic activator such as Permabond A905 may help achieve faster cure speeds.
How Does an Anaerobic Threadlocker Work?
Anaerobic adhesives remain liquid while exposed to air. Once applied between close-fitting metal threads, oxygen is excluded and the adhesive cures to form a strong polymer that locks the fastener in place.
This not only prevents loosening caused by vibration but also seals the threads against the ingress of moisture, oils and other contaminants that can contribute to corrosion.
Why Choose Permabond A1042?
Mechanical locking methods such as spring washers and lock nuts can lose effectiveness over time, particularly in high-vibration environments. Permabond A1042 provides a more reliable solution by chemically locking the entire threaded assembly while maintaining the option of future disassembly for servicing.
Whether you’re assembling new equipment or carrying out maintenance repairs, Permabond A1042 offers dependable performance across a wide variety of industrial and engineering applications.
