About Structural Adhesives

Threadlockers

Prevent threaded fasteners from loosening due to shock and vibration.

Heavy Duty Threadlockers

Withstand demanding, high-vibration applications such as motor and pump housings with these threadlockers.

Adjustable Threadlockers

Use these threadlockers on fasteners that require occasional fine-tuning, such as set screws.

Threadlockers for Drinking Water

These threadlockers are meet NSF/ANSI 61 for drinking water.

High-Temperature Threadlockers

Keep threaded fasteners from loosening at temperatures up to 450° F.

Threadlockers for Plastic Fasteners

Specially formulated for plastics, these threadlockers secure nylon, PTFE, and other plastic threaded fasteners.

Quick-Set Threadlockers

These threadlockers develop usable strength within one hour. Because they harden quickly on most metals, they don't require a primer.

Lubricating Threadlockers

These low-friction threadlockers harden slowly, allowing ample time to smoothly adjust multiple large bolts for even clamping.

Threadlocker Paste

Paste threadlockers are easy to apply and won't drip, even from overhead fasteners.

High-Temperature Threadlocker Paste

This thick paste withstands temperatures up to 650 °F.

Threadlocker Gel

This gel clings to fasteners to prevent drips.

Wicking Threadlockers

Apply these threadlockers on fasteners that are already installed—their thin consistency allows them to flow into small gaps.

High-Temperature
Wicking Threadlockers

These threadlockers withstand temperatures up to 450° F.

Adjustable Wicking Threadlockers

Use these threadlockers for threaded fasteners that require occasional fine-tuning, such as set screws.

Threadlocker Tape

Wrap this no-mess tape around threaded fasteners up to 30 days before installation.

Thread Sealants

Thread Sealants with PTFE

These sealants come in bottles, cans, and tubes so you can choose the quantity that covers your application.

Drip-Free Thread Sealants with PTFE

Apply this thread sealant stick without a mess.

Non-Hardening Thread
Sealants with PTFE

Thread Sealants

These sealants come in bottles, cans, and tubes so you can choose the quantity that covers your application.

Non-Hardening Thread Sealants

Often used in high-vibration applications that could cause standard thread sealants to fail, these never fully harden and remain pliable enough to self-heal and stop leaks before they start.

Thread Sealants for Hydraulic
and Compressed Air Systems

Formulated for high lubricity, these sealants allow easy assembly of finely threaded hydraulic and compressed air system components. They're also free of fillers that could contaminate system media.

Thread Sealants for
Refrigeration Systems

For use in refrigeration systems and applications exposed to strong chemicals, these sealants have excellent solvent resistance.
