Why Do More Engineers Choose Security Locknut?
How it Works
The key to Security Locknut’s performance is in the spring-steel lock ring. While other’s have tried to imitate our design, no other solution on the market comes close to our performance because of the unique way in which our spring-steel lock ring is engineered & manufactured. The amazing technology behind our spring-steel lock ring results in incredible rotational resistance for securing the locknut, while at the same time allows for ease of installation. The ring material is based on a durable spring steel alloy which doesn’t distort the threads of the bolt. This means repeatable performance even after the locknut has been removed and reinstalled dozens of times.
How it Works
Vibration testing using the NASM 1312-7 protocol. This standard that establishes a procedure for conducting accelerated vibration tests on any fastener system capable of providing a clamp-up load. The bolt/nut combination is installed in the fixture, the fixture is subjected to controlled vibration and times/cycles until the assembly loosens. The Security Locknut performed exceptionally well in tests against other commonly used products. A summary of the test results are shown below.
|Product||Cycles to loosen||Cycles to fall completely off|
|Security Locknut||55,000||Never **|
|Conical (or Top lock) Locknut||2,000||6,000|
|Standard + split washer||100||500|
|* * Test stopped after 90,000 cycles|
