And that’s it! A helicoil installed with LOCTITE® 2620™
won’t ever retract if you need to remove the fastener.
Can You Use LOCTITE® 262™ Threadlocker?
In short, the answer is yes. LOCTITE® 262™ is a high-strength threadlocker just like LOCTITE® 2620™, but can withstand up to 360°F rather than the 650°F that LOCTITE® 2620™ can withstand. LOCTITE® 2620™ was chosen for that reason, and because it tolerates surface contaminants from lubrication, anti-corrosion and protection fluids well. If using LOCTITE® 262™, just apply it into the fresh-cut threads prior to inserting the coil; insert the coil; and let it cure.
Can You Use LOCTITE® PC 3967™ Stripped Thread Repair Kit Instead?
In some cases, LOCTITE® PC 3967™ Stripped Thread Repair Kit (Known as LOCTITE® Form-A-Thread®) has been used as an alternative to helicoils. This stripped thread repair method restores worn, stripped or damaged threads without drills, tools or inserts.
It’s a five-minute job, with a finished assembly that allows up to 128 ft. lbs. of torque within a wide temperature range. However, an application assessment should be performed to determine suitability, and keep in mind that even in those instances when PC 3967™ would be effective, helicoil repairs are always stronger.
