ABB 3HAB7116-1 Loctite 243 Locking Liquid

Threadlocking Adhesive for ABB Robot Assembly and Repair

Specifications

Industrial Applications

• Locking attachment screws during ABB robot assembly and after reassembly from repair, so joints stay tight through continuous motion.
• Securing fasteners on cable-package and dresspack fittings (for example the DressPack IRB 6640) that would otherwise work loose under the robot's movement.
• Field-service and planned-maintenance kits where a procedure explicitly calls for a threadlocker at a named step.
• Vibration-prone joints on robot bases, arms and dresspacks running high-cycle production.
• Preventing fastener loosening that leads to misalignment, noise or dropped components on automated lines.
• Stocking the exact ABB-specified consumable so a service procedure is never held up waiting for the right grade of locking liquid.

Design Purpose

A threadlocking adhesive is a liquid that cures in the absence of air between close-fitting metal threads. Once applied to a screw and tightened, it fills the gaps in the thread form and sets into a solid that stops the fastener from rotating loose under vibration, while still allowing later disassembly with hand tools at the specified grade. ABB does not leave this to chance: in its robot service manuals the consumable appears by article number — 3HAB7116-1, named "Loctite 243", "locking liquid" — under a "Required consumables" heading, with the note "For locking attachment screws". The article number is how the procedure stays reproducible: whoever runs the job reaches for the same specified consumable, not a tube pulled from a generic shelf.

What makes a specified locking liquid worth calling out on its own page is that robots move all day. Screws on moving joints see cyclic loads and vibration that, without a threadlocker, can back out over time and let a joint develop play, noise or misalignment — sometimes only showing up later as a quality or downtime event. ABB's answer is to lock the attachment screws with the consumable it specifies, which holds the fastener without the permanent bond that would make the next disassembly a fight. Because 3HAB7116-1 is a consumable rather than a spare part, the right page is less about "which robot does it fit" and more about "which procedure calls for it" — and ABB's manuals call for it across several robot families, which is why it is a sensible item to keep on the maintenance shelf.

Common Failure Modes

• Screws loosening and backing out under vibration because no threadlocker was applied at assembly or reassembly.
• Joint play, noise or misalignment developing after a fastener worked loose, sometimes only visible as a later quality or downtime event.
• Cross-threaded or damaged threads from reusing a fastener without re-applying the consumable.
• Wrong-grade substitute that either will not hold the screw or cannot be disassembled without damage later.
• Adhesive failing to cure because the threads were oily, greasy or contaminated.
• Excess liquid migrating into bearings, sensors or seals and causing a separate fault.
• Using a non-ABB generic that does not match the article the procedure specifies.
• Stock-out: a repair stalls because the specified locking liquid was not on the shelf when the procedure called for it.

ABB does not publish an alarm code for a missing or failed threadlocker — loosening normally shows up later as a mechanical or positioning fault. Please contact us with the fault code displayed on your controller for accurate diagnosis.
