Does your company need thread lockers, nylon patches, or nylon pellets pre-applied to your fasteners?
Save time and valuable resources by turning to AFT Fasteners for pre-applied thread lockers and nylon patch screws and other fasteners. Thread-locking fluid, or thread lockers is a type of adhesive that is applied to the external or internal threads of fasteners, such as bolts, nuts, lock washers, and screws to prevent loosening, leakage, and corrosion. Threadlockers are used in a wide range of industries, from automotive and aerospace, to manufacturing and construction, where fasteners are prone to vibration or highly corrosive environments.
Types of Threadlockers
There are 2 main types of thread lockers currently available: inert thread lockers and reactive thread lockers. Also known as prevailing torque, inert thread locking creates a secure fastening lock, which is resistant to vibration and shock related slippage. Reactive thread lockers are comprised of a chemical bond which is formed from the adhesive, preventing slippage from shock and vibration while helping to seal fastening points against gas and liquid leakage.
AFT offers many different types of both pre-applied inert and reactive thread locking processed as well as user-applied (bottled) thread lockers. A few options include: permanent and removable thread lockers, thread lockers for wood/plastic/nylon materials, reusable thread lockers, thread lockers that require or doesn't require drilling, and chemical-resistant thread lockers.
We use the highest-quality products and have the ability to work with anything from standard fasteners to custom products. As with most of our services, AFT offers our customers the option to either purchase the fasteners directly through AFT or supply their own parts. Most of the thread locking and nylon patch options available through AFT are listed below, however please ask if you require a product or process not currently listed on our site. We'll do our best to meet your thread locking requirements.

Nylok® Blue Nylon Torq-Patch Tuflok
|
Nylok® Blue Nylon Torq-Patch® Tuflok® is a self-locking element comprised of nylon permanently bonded onto the threads of a fastener. When the Nylok® Blue Nylon Torq-Patch® Tuflok® is engaged, it creates a wedge between the fastener and mating part compressing the nylon and creating metal to metal contact opposite the patch. This metal to metal contact results in a positive resistance to vibration and loosening. Since nylon has great memory characteristics, this locking element can be reused several times. Min Temp -70 F, Max Temp 250 F |
|
NylokHD® Patch
