A key lock insert tool is a solid cylindrical lining style insert that is threaded internally and externally and has sections or “keys” fixed at the top. These inserts allow loads and reparation or reinforce threads against seizing, stripping, or corrosion failures. Generally, people use these inserts for precision manufacturing, and also they are beneficial for aerospace applications.
They are used in surroundings with a lot of torque, vibration, and even in high-temperature applications. They are also occasionally used in things where a fastener is replaced, taken out, and reassembled.
Here we will compare two standard fastener products that help repair damaged threads or support a weaker parental substantial like aluminum: Helical Wire Inserts and Key-locking Inserts. Both are helpful in industrial manufacturing and aerospace applications.
What is a Helical Insert Wire Insert?
The underrated general misconstruction is that Helical wire inserts are envisioned exclusively for thread repair, but they have other substantial uses. Helical wire inserts are correctly-formed, unceasing wire coils that offer permanent, wear-resistant threads surpassing the parental material’s strength. Not to be confused with different types of threaded inserts, Helical wire inserts look like springs and are referred to as”Screw Thread Inserts (STI).”
Three distinctive applications for using Helical wire inserts are
1) it is helpful for the reparation of damaged threads in parts that would then have to be sparred;
2) people use it to strengthen the threads against failures due to seizing, stripping, or corrosion;
3) to change threads among inch and measured sizes.
What is a Key-locking insert?
The key lock insert tool is a tool that helps to hold them in place. Also, it helps in the reparation of damaged threads with an optimistic automatic lock, stopping rotational spinout from trembling or torque. These inserts are for metallic applications, not suggested for cast iron or brittle substantial.
Also, they are beneficial for use in high torque and high-temperature circumstances and in bids where fasteners may be constantly removed and collected. Also, they are perfect for thread reinforcement, particularly when you remove the bolt or the mating stud frequently. These key-locking threaded pull-outs offer robust and permanent steel threads in a frailer parent material –non-ferrous, ferrous, or non-metallic
Specific applications are electronic equipment, broadcast housings, and suspension units. Key-locking inserts are present in aerospace assemblies.
Key-locking insert vs. Helical wire insert
There are three foremost variances among Key-locking inserts and Helical wire inserts are:
1) Strength: the Key-locking inserts are more significant than Helical wire inserts
2) Ease fitting: you can easily install Key-locking inserts. However, you require more effort in the helical insert.
3) Cost: Key-locking inserts are more exclusive than Helical wire inserts
So, some of the best applications for using the thread insert are: In high vibration, heavy wear, and high heat situations where convertible space is not a worry and hole depth are limited, Key-locking inserts are the top bet. So, look at these things before purchasing a threaded insert for your work.
