TrueLock Bolt (TM) - A bolt with positive, continuous, mechanical locking and unlocking in an infinite number of positions

A bolt is a bolt, is a bolt, is a bolt...
Right?
Right... as long as it doesn't loosen in service under vibration and shock loads!

Otherwise, it’s no longer a bolt, but a major problem with potentially disastrous consequences,
especially in mission-critical applications.

So far, there’s been no bullet-proof solution
to the problem of vibration-induced bolt loosening. Now there is the...

Positively Locked - Precisely Where You Want,
And With Indefinite Reuse Of All Components

TrueLock Bolt™ For Helicopter Main Rotor
1¼ Inch-Diameter, Heavy Series — Titanium

The TrueLock Bolt™ ⁽*⁾ provides positive, continuous, mechanical locking, and unlocking, in an infinite number of positions, precisely in the exact final clamping position of the bolted connection – all at substantial cost savings.

The TrueLock Bolt™ passed successfully rigorous vibration and shock testing to US DOD:

MIL-STD-167-1, Vibration - US Navy
MIL-S-901D, Shock - US Navy
MIL-STD-810F Method 514.5, Vibration - Aerospace

for use in super-critical industrial, defense, and aerospace applications,
such as – but not limited to – landing gear and jet engine mounts of commercial and military aircraft,
helicopter main and tail rotor bolting, gas turbines, weapons, ships, aircraft carriers, and submarines;
all applications where failure is not an option.
