Loctite Threadlockers


LOCTITE threadlockers are one of the most reliable and inexpensive ways to make sure a threaded assembly remains locked and secured for the entirety of its service life. Usually applied drop-wise to fastener threads, liquid LOCTITE threadlockers can fill all the gaps between the mating threads. Post application, they solidify to form a hard-thermoset plastic which locks the threads together and prevents unwanted loosening, leakage, and corrosion.
LOCTITE vs Double Locknut
Adding an additional nut does not eliminate the gaps which LOCTITE can fill completely.
LOCTITE vs Spring Washer
The spring action created by the washer cannot eliminate the gaps which LOCTITE can fill completely.
LOCTITE vs Nut with Nylon Insert
Nylon Insert increases resistance to loosening but does not eliminate the gaps which LOCTITE fills completely.
LOCTITE vs Castellated Nut with Split Pin
While the Split Pin can prevent fastener loss, it does not eliminate the gaps which LOCTITE can fill completely.
LOCTITE vs Ribbed Flanged Bolt
The bolt digs into surface increasing clamp load but does not eliminate the gaps which LOCTITE fills completely.
WHY CHOOSE LOCTITE THREADLOCKERS?

Lock threaded
assemblies against
vibrational loosening:
- Fills 100% of the gap
between threads of nut
and bolt which eliminates
the root cause of
vibrational loosening

Outperform All
Locking Devices:
- Better clamp load
retention compared to all
mechanical locking devices

Increase End Product
Service Life:
- Higher off-torque
provides
additional safety

Prevent Galling
and Corrosion:
- Protects against corrosion
by forming an impenetrable
layer between nut
and bolt threads - Liquid film prevents friction
welding or galling between
nut and bolt threads

Permit Disassembly:
- Low and medium grades
allow disassembly with
standard hand tools

Minimize Inventory Cost and Complexity:
- One size fits all - applicable
for a wide range of
fastener sizes

Save Cost:
- Lower cost per unit
compared to most
locking devices

Increase Durability
- Thermal Resistance of
up to 150 C and higher - Able to withstand most
industrial gases and fluids - Field proven for decades
HOW TO SELECT THE RIGHT LOCTITE THREADLOCKER?
To choose the best threadlocker, simply answer these three questions:
- What is the fastener size?
- What is the required strength?
- How frequently do you service the equipment?
